Before my work gave me a laptop, I was looking at the X1. Does it have bluetooth? Personally, if I have to use a trackpad for periods longer than 5 seconds, I start to go insane. I can't stand those things. The only pointing device that's worse is those damn eraser head things in the middle of laptop keyboards.

So I carry one of these around in my laptop bag. I love it, and never use my laptop without it. Seriously, I can't recommend it highly enough. It's tiny, bluetooth, and has a much better feel than you would think. I've grown so acustomed to it that when I use standard mice they feel enormouse in my hand
