I looked at all kinds of tablets, but then I realized I could get more functionality, roughly equal portability and battery life, for a much cheaper price.
My ASUS netbook was the best money I've ever spent.
For $250, I got:
-A 10.1 inch screen
-9-10 honest hours of battery life if you're conservative
-A 1.5GHz dual core processor fast enough to watch 360p videos while running Visual Studio and Eclipse
-2GB of DDR3 RAM
-A 250GB HD
-3 USB 2.0 ports
-Ability to dual boot Win7 Pro and Linux
-A keyboard
-A webcam
-All in a device that weighs less than 3 pounds and fits easily in any small bag.
It blows my mind that people would want to spend $300+ on a device with slightly more portability and far, far less functionality.
