Lenovo Thinkpad T430s Review (i5 with Nvidia Optimus)

June 24th, 2012 21 comments

I’ve had a Thinkpad T410s for the past 2 years, but the non-Trim Samsung hard drive was hurting my productivity, and IT agreed to buy me a new computer. Naturally, we turned to the recently released T430s. As I really wanted to run 3 displays with the Series 3 Mini Dock Plus I already had, we decided to get the Core i5 model with Nvidia Optimus graphics. I’ve had the machine now for a few days, and while I’m still waiting to upgrade from 4GB to 16GB of RAM, I thought I’d share some thoughts and benchmarks for those who may be considering purchasing this machine.

4 simple tips to get you ahead of 80% of job applicants I’ve reviewed

January 11th, 2012 3 comments

I thought most of these things were commonly taught in school, but based on many job applications I’ve recently reviewed, applicants either don’t know or are ignoring them. Don’t let it happen to you.

1) Write a cover letter. Just create a nice, two paragraph letter that briefly covers your background, skills, and interests.

2) When you apply, add a couple sentences to your cover letter about why you think you are a good fit for the job. This should show that you’ve at least taken 5 minutes to read the company website and learn what it is that we do. A totally generic cover letter is just as bad as no cover letter at all.

3) If you are given any type of homework, or even just some emailed questions to answer, finish it as soon as possible. It will take the same amount of time to complete no matter how late you do it, but you will appear much more interested and competent if you complete it in a day rather than a week.

4) If you have any questions about anything in the interview process, such as homework, interview timing, or even the dress code, ask about it early on. It’s much better to make sure you are on the right track than to go down the wrong path and waste everyone’s time. Asking questions makes you look more professional, not less.

Remember, a job interview is a privilege, not a right. If you don’t put some time and energy into applying for the job, I’m not going to waste my time and energy interviewing you.

Meebo Auto-Away Chrome Extension

September 24th, 2011 No comments

It’s been pretty quiet around here, but I’ve finally motivated myself to publish a new Chrome extension: Meebo Auto-Away. This superceeds my old desktop program, and provides much smoother functionality.

Meebo Auto-Away is a small extension that allows you to specify idle time (in seconds), and away message, and a back message. It will only function if you are signed into in a Chrome tab.

When your computer has been idle for the specified number of seconds, your Meebo status will automatically be set to away using the provided message. When you return from being idle, you will automatically be set to available using the provided back message.

If you wish to hide the Meebo Auto-Away icon, you can right-click on it and select “hide icon”. You can still manage your settings by navigating to Tools->Extensions and clicking the “options” link for Meebo Auto-Away.

You can install the most up-to date extension from the Meebo Auto-Away Chrome Extensions site. Alternately, you can install this .crx file.

Questions, comments, and general feedback can be sent from my contact page.

Meebo Auto-Away – Set to Away When Idle is Detected

October 24th, 2010 1 comment

This program has been superseded by my Meebo Auto-Away Chrome Extension.

Meebo Auto-Away is a simple program that detects your computer’s idle status and sets your Meebo status to away after a defined amount of idle time.


Over the years, I have used a number of instant messaging aggregators, but my favorite so far has been Meebo, a free, web-based tool that can handle the usual suspects, like AIM and MSN, but also ICQ and Facebook. In addition, because it is web based, I can log on from any computer and access my organized friend list and view the history of my messages.

My major complaint with Meebo has always been that it does not set users to away when the computer has been idle, a feature that is present on most modern instant messaging applications. The reason is that a web application cannot access the operating system to determine how long the computer has been idle. I had hoped that the Meebo notifier, a desktop application, would handle this functionality, but, alas, it does not.

After having several people continue to message me even though I had been away from my computer for hours, I decided that I needed to do something to solve this problem. Meebo has no public API, so I couldn’t simply write a program that checked the computer’s idle status and set a user to away through a backdoor channel.

Instead, I went through the front door, embedding a browser into a .Net application that I’ve christened Meebo Auto-Away. Essentially, a user logs into Meebo through the embedded browser, but Meebo Auto-Away can determin a user’s idle time and set the user to away the same way that a web browser does.

Using Meebo Auto-Away

To use the program, simply download the executable and run it (you will need a Windows computer with .Net installed). After the application starts, you can enter the number of seconds you would like the program to wait before setting you away and the away message you would like displayed. You can then log into Meebo through the embedded web browser. You could actually use Meebo Auto-Away for all of your instant messaging, though I would recommend minimizing it to the system tray and using Meebo in a full browser (Meebo handles multiple sessions very well).

You can save your current idle time and away message values as the default in the file menu. Meebo Auto-Away connects through https, so your session is secure. I do not collect any data from the Meebo Auto-Away application or install any other applications. This is a personal program that I created for my own use, and I am sharing so that others frustrated Meebo users can also enjoy setting their status to away on idle.

If you have any questions or find any bugs, feel free to post them in the comments.


Note that this application is freeware. I am not an employee of Meebo or associated with them in any way, save that I use and appreciate their application. By downloading, you agree that you are using Meebo Auto-Away at your own risk. I am not responsible for any issues that result from using Meebo Auto-Away.

Latitude XT2 With SSD Review Update

March 9th, 2010 No comments

In a previous post, I reviewed my Latitude XT2 Tablet PC with Windows 7 Beta, and I noted that I may buy an SSD in the future. Well, the future is now, and I recently purchased an Intel X-18m second generation drive and installed it in my computer.

Quantitatively, the numbers show a marked increase in both the Windows Experience Index and the HD Tune results, seen below. Qualitatively, the difference is amazing. My computer boots from a cold start to a working desktop in under 20 seconds, and it takes mere seconds to install a program like Firefox. It almost feels like I have a whole new computer. Certainly worth the ~$230 for the 80 gigabyte drive.

Apple iPad vs. Tablet PC: A Comparison

January 28th, 2010 14 comments

With the recent announcement of the iPad, I thought this would be a good time to do a comparison with the modern Tablet PC. As an on and off user of Tablet PCs for the past 7 years, I’ve had a lot of experience with the platform as it has moved from Windows XP Tablet Edition and Pentium III processors to modern Windows 7 versions on Core2 Duos. Still, I’m intrigued what Steve’s demonstration yesterday, and while I obviously haven’t had a chance to hold the new iPad, I have watched a number of demonstration videos and read several hands on, and I’ve used an iPhone on and off for almost two years. Thus I feel qualified enough to do a high-level comparison between the Apple iPad, and my Tablet PC, the Dell Latitude XT2.

Wi-Fi & Bluetooth Yes Yes
3G Optional, through AT&T at a discount Optional, through AT&T, Verizon, or Sprint
Connectivity Ports Docking connector, headphone, mic 2 USB, 1 USB/eSata, Expresscard, SD Card, Gigabit Ethernet, VGA, headphone, mic
Accelerometer Yes No
Build-in Hardware Keyboard No Yes
Multitasking No Yes
Adobe Flash No Yes
Built-in Camera No No
Applications available Select iPad apps at launch, including iLife, 140,000 scaled iPhone apps Complete Windows library
Price Begins at $499 Begins at ~$1999 ($999 refurbished)


The Latitude XT2 has a larger, more high resolution screen with the added advantage of having a built in stylus, which gives it the win here. The stylus also allows for effective note scribbling, something that is difficult to do with fingers. That being said, even with Windows 7’s new gesture support, Tablet PCs just don’t have the finger-friendliness of the iPhone, and, as an extension, the iPad. The iPad’s screen also looked a little brighter, and overall more fun to use.


While my XT2 feels fairly light, the added components and keyboard can’t compete with the slim, streamlined iPad. While I haven’t held one in my hand, I have to imagine that an iPad would be more comfortable for long periods of reading or browsing, though I haven’t really had issues with my XT2.


Apple has flexed its hardware muscles after the acquisition of P.A. Semi almost 2 years ago. The 1Ghz ARM-based A4 chip appears to be very fast, especially when paired with Flash memory and optimized software. The Core2 Duo chip in the XT2 may be a little faster, but without the level of software optimization that the iPad has, I’m going to rate this as a tie.


The iPad can hold up to 64 gigabytes of flash memory, compared with 256 gigabyes for the XT2 (and likely 512 gigabytes soon). Download some high-definition movies, and 64 gigbytes goes pretty fast. In addition, the XT2 can use ExpressCard and USB external storage and even USB Blu-Ray drives.

Battery Life

With 10 hours of battery life, I’m going to have to give this one to Apple. The Latitude (and most Tablet PCs) can get an extra battery, but it adds cost and weight. The iPad battery is not removable, unfortunately, but this seems to be the Apple trend of late.

Wireless Connectivity

Both machines have full 802.11 a/b/g/n Wi-fi and Bluetooth, and also 3G access. The Latitude offers a greater variety of carriers for 3G, but the iPad has a much cheaper data plan at $30, so I’m calling 3G as a tie, depending on whether you value price or flexibility.

Connectivity Ports

This is where the decision to make the iPad a larger iPhone rather than a small Macbook begins to hurt. The lack of any real connectivity options means that it will be difficult to expand the iPad’s built-in memory, and a large range of USB devices, such as webcams and DVD drives, are not going to be available. The docking connector does allow video out with an adapter, but at a paltry 1024×768 resolution (the XT2 does up to 1920×1080 over VGA, and can do HDMI over the docking station).

Accelerometer/Keyboard and Gaming

The lack of a hardware keyboard on the iPad will probably be more off-putting than the lack of an accelerometer on the XT2. The XT2 can also use a mouse, which allows for a wide variety of mouse/keyboard gaming options. While I’ve enjoyed the accelerometer on my iPhone, I generally find it a bit gimmicky for gaming, and first-person shooters just don’t play well with touch-screen controls.


Another major Achilles heel for the iPad, and something I really hope is fixed in the iPhone OS 4.0 update. The lack of multi-tasking is problematic enough on the iPhone, but I know I’ll really find myself missing it on the almost 10″ screen. Why can’t I run an IM window next to my Flash game with Pandora streaming in the background (a common occurrence on my XT2)?

Adobe Flash Support

Similar to multi-tasking, this moves from a weakness on the iPhone to a serious flaw on the iPad. Steve called out the iPad as the ultimate browsing experience, especially over “underpowered” netbooks, but browsing without Flash means a decent chuck of the web is not available. Again, I’m keeping my fingers crossed for an OS 4.0 update, but I see this as less likely than multi-tasking support, though arguably more important.


I think that App developers may come up with some really neat applications for the iPad, but for the present, the 140,000 pixelated iPhone apps don’t compare with the huge library of Windows software available. In addition, Apple has rather draconian application development policies. Without full access to the iPad file system and hardware, I fear that it will again fall on the jailbreak community to develop useful utilities.


Tablet PCs have failed to get mass-market adoption for almost a decade, and a major reason is that they are more costly than a laptop with similar specs. Apple made a smart move by offering a model with less persistent memory and no 3G at a lower price point. To be fair, the XT2 is one of the most expensive Tablet PCs on the market, as you can find models like HP’s Touchsmart at a $949 price with up to 20% discounts. In addition, most people using Tablet PCs do not have another laptop, which many iPad users will still want to price in a laptop as well as the iPad, leaving less available budget. Still, the bottom line is that the iPad runs away with this one.


The iPad has received its share of criticism in the past 24 hours, and much of it centers around a key design reality: the iPad is not a “Macbook Light”; it is an “iPhone heavy”. As a result, it has significant weaknesses compared to traditional laptops, unlike Tablet PCs, which are “Laptops Plus”. The comparison chart illustrates this, as the iPad only really wins on weight, battery, and price. The iPad is really for people that want a lightweight, cheap, limited device in addition to their laptop or instead of their laptop. In that respect, it fills the same niche as netbooks and eReaders, rather than today’s Tablet PCs, and netbooks and eReaders will be the real competitor, especially as more netbooks add touch capabilities.

The final piece of the puzzle is the full iPad experience. On paper, the iPad has a tough time competing with today’s Tablet PCs, and even today’s netbooks in many respects. Having not held one in my hand, I haven’t had the “magical” experience, but a combination of killer apps and a seamless, pleasurable UI may allow the iPad to make a name for itself. Time will tell.

As for me, I’m still waiting for the Microsoft Courier.

3 tips on designing an effective e-commerce checkout

November 27th, 2009 No comments

Of the many different types of websites, none has received as much scrutiny as e-commerce, a category where ROI can be measured more easily than any other. And in e-commerce sites, the most studied area is the checkout, a multi-step process where users often fall off before completing their purchase. In my own research attempts, I found considerable amounts of information, but little written from a usability design perspective.

In this article, I will highlight three important steps that can be taken to improve the usability and ultimately the success of an online checkout. Many of these suggestions are based on common user experience design heuristics, the most well-known having been produced by Jakob Nielsen. These heuristics are violated both consciously and unconsciously, often by designers or clients who feel that users should be funneled through a checkout to the point that information and paths that would allow a user to postpone a purchase are removed. Unfortunately, this often leads only to frustrated users who will be unwilling to complete a purchase.

Tip #1 – Provide clear direction of paths on the sign-in page

amazon-sign-in lenovo-sign-in
Problematic Example – Good Example –

When a user makes the decision to check out, they need to see sign-in options. A user may already have an existing account on the site, or they may be completely new. In addition, some new users may wish to create an account on the site, while other users simply want to check out as quickly as possible. A single page is usually necessary to direct these different types of users to the proper path.

Such a page should contain at least 3 elements:

  • Username and password fields and a sign in button for existing users.
  • A button or link for users that wish to create an account.
  • A button or link for users that wish to check out without creating an account (often called Guest Checkout).

Sometimes account creation is tied in as an optional step in the Guest Checkout, but if so, this should be clearly indicated on the page. In addition, many sites support 3rd party payment and checkout options like Paypal or Google Checkout, and these options should be visible on this page as well.

While most e-commerce sites include these elements, the presentation often suffers. One or more options may be overshadowed by another, or widget placement makes it difficult for users to understand what they need to do for each path. For example, the Amazon page uses the same form field and action button for both new and returning users, and uses a radio button to select user type. This blurs the line between the paths available, and leads many users to encounter error messages or begin down the wrong path. In addition, there is no guest checkout.

In contrast, the Lenovo e-commerce site uses the page architecture and design to clearly lay out the path for returning and new users. For new users, both the account sign-up and Guest Checkout are clearly visible.

Tip #2 – Let the users know where they are

zappos-address k-mart-address
Problematic Example – Good Example –

From Jakob Neilson’s 10 heuristics to Keith Instone’s Stress Test, user experience experts agree that it is important for users to be aware of their position in a website. It stands to reason that users should easily be able to access relevant information about their position and step in the checkout process. Designers may balk at including this information, saying that it will clutter the page and overwhelm the users, but good designers can work this information in an effective way. The following should be available on all steps of the checkout, not just the final Review and Confirm:

  • Clearly define the number and name of each step in the checkout process (usually at the top of the page).
  • Show the user where they are in the checkout process.
  • Clearly indicate what the user needs to do to continue by highlighting the Continue button and giving it a label that describes the next step
  • Show the user relevant information from previous steps, such as items in cart, shipping costs, total costs, shipping addresses, etc.

Zappos demonstrates a lack of useful information. The Zappos checkout does not even include a listing of the steps in the checkout process or a clear header that describes the current step. There is no information about the items in the user’s cart. Despite the lack of this important information, the page is very cluttered and text is tiny and difficult to read. Even the Continue button, which should pop-out, is buried under text.

In contrast, the K-Mart site is clean and contains significant amounts of white space, yet also provides relevant information to the user. The graphic at the top of the screen illustrates the steps in the checkout process and uses color to clearly show users where they are in the process. Information about the users order is provided in the right hand column, including a full breakdown of cost. Finally, the Continue button is clearly visible and well-positioned at the bottom of the form, though the labeling should call out the next step, such as “Continue to Shipping Options”.

Tip #3 – Let the user move freely

buycom-address checkout
Problematic Example – Good Example –

Steve Krug, in his slightly dated, yet still excellent web usability book, Don’t Make Me Think, uses an e-commerce checkout as an example of a page where global navigation may not be necessary, though he still recommends a minimal navigation with a home link. Personally, I cringe at the number of e-commerce checkouts that remove most or all navigation options from the checkout pages, forcing the users down a narrow funnel. The problem is that some users may wish to leave the checkout for a variety of reasons but still come back. Perhaps they think of another item they wish to purchase, or want to fill out there cart to reach the minimum purchase threshold for free shipping. Many clients feel that they need to remove anything but the Next Step link in a checkout in order to drive users to complete their shopping. Unfortunately, boxing these types of users in will not push them toward completing their transaction. Instead, these users may become frustrated and abandon the checkout all together. The following should be available throughout the checkout process:

  • Global Navigation. Users have come to rely on it throughout their shopping experience. Taking it away reduces the users control and navigation options, and can raise a flag for the user if the look and feel changes enough to make them feel they have gone to another site for the checkout.
  • Back to cart button. Users that need to alter their cart should have a clear way to do so, in addition to visualizing their cart during every step of the checkout process.
  • Clearly labeled Next Step button. This was mentioned earlier, but it bears repeating. The button should be visible and pop out on the page.
  • Review and Confirm Step with links to each step in the checkout process, including their cart. The user needs to know that they have a last chance to look things over. If their is a problem with their information or cart contents, they should be able to easily change them.

The checkout removes the entire global navigation, replacing it with a checkout progress indicator and logo. Unfortunately, neither are clickable, leaving the user with “Save and Continue” as her only option. The lack of the global navigation menu also changes the look of the site, though the color scheme and logo keep the site from appearing too jarring. In its defense, the Review and Confirm page does include links to change a shipping address or go back to their cart, though these links are very small and easy to miss.

In contrast, the checkout includes the global navigation throughout the checkout process, adding the checkout navigation as an additional, prominent piece of information. A clearly visible Back to Cart button is also visible on all steps, and the user can easily change her shipping information from the previous step.

Conclusion and a few words on one page checkouts

So that concludes my three tips, which boil down to two important web heuristics: give the user sufficient information about where they are and where they can go, and give the user the freedom to move where they wish to.

A final point I wish to touch on is the idea of a one-page checkout. Some sites, such as, will use small points, four columns, and a scrolling page to fit all of a users shipping and billing options on one page. This is problematic for several reasons, not the least being an information overload. Other sites, such as, use an AJAX driven interface to expand and collapse different steps in an acordian fashion, retaining a multiple step process without forcing a single page load. While this solution has its merits, it is important to consider the accessibility implications of implementing a checkout that relies so heavily on JavaScript, particularly in light of ADA (Americans with Disabilities Act) lawsuits such as the one that hit Target 3 years ago. In addition, users have become familiar with the three-page checkout, and a new paradigm may confuse some users. That being said, there is clearly a future for checkouts like checkout (AJAX expandable) checkout (AJAX expandable)
