Lenovo ThinkPad T Series: T400s
The Lenovo ThinkPad T Series T400s touch screen laptop is a real heavy weight in the world of touch screen computing. Not only is it packed with a lot of computing muscle. It is also one of the first to be equipped with a four finger capacitive touch screen. A capacitive touch screen has an electric current running through a conductive coating on a glass panel. When a person touches the screen there is a change in capacitance at that point and the computer registers the exact point where it was touched. This type of touch screen requires very little pressure and the image clarity is generally extremely sharp and bright.
The T400s comes bundled with Windows 7 and it takes full advantage of the new operating system’s touch screen capabilities. It also has it’s own support software called SimpleTap to make interacting with with computer even easier.
This unit supports multi-touch functionality and as mentioned earlier, the touch screen can recognize up to four fingers at once! I have no idea when you would actually use four fingers at once to interact with it though. This seems like a bit of a marketing gimmick to me. Maybe there will be a use for it in the future but I can’t think of one now.
Battery life tests for this laptop resulted in an average run time of around four hours which seems to be in line with other touch screen laptop models. One thing that is very cool is that you can buy an extra battery which they claim will increase the battery run time to eight hours.
One area that this touch screen laptop really falls short is that the screen doesn’t rotate and fold flat for full tablet functionality. I have no idea why they would omit this feature. This seems like a major oversight in my opinion.
The capacitive touch screen is ultra responsive and and this laptop is packed with some serious muscle. The MSRP for this model is around $1500.

You can open the computer, put your finger on the fingerprint reader and the computer will instantly power up. With the solid state hard drive, the computer powers up in about 40 seconds.
