The main reason I went with this one is how light/small it is and it still has a good keyboard. It weighs less than 2.5 pounds and easily fits in my backpack.
I am writing this from a restaurant. I have been running with the extended battery (comes with a regular and extended standard). I've been here for more than 2 hours and my battery indicator says I can go for another hour. I haven't done any tweaking to conserve power, so I could probably go longer. With the settings I have on now, the computer is very responsive and the screen is nice and bright.
I am using my AT&T Tilt's Bluetooth connection for Internet access.
It has a very unique/engaging look...which is very important around here when you have to do battle with all the Apple-fanboys.
The face recognition (via integrated web cam) login works surprisingly well, as long as the light is decent. At first I thought this would be a gimmick, but I rarely type my password anymore. As soon as I sit in front of my laptop, it logs me in. You also have the option to use your face for Internet passwords, which is very handy.
I got my laptop from J&R. I bought it for $1999, which was $100 more than what you get if you order from Lenovo directly. Currently, you can't configure the laptop. However, the version from J&R has integrated Bluetooth and 3GB of RAM (Lenovo's site is selling 2GB of RAM with no Bluetooth). Bluetooth is critical for me because I expect to use it for my Internet connection and I don't want to deal with add-on cards. The extra RAM is nice, but I don't actually need it for what I'm doing
So far, I love it.
I plan on using it for email, Internet, blogging, and a C# project I've been planning for a while.
Here is a video to get an idea of what it looks like. It definitely draws attention.
