I have the Kindle touchscreen. I got it in 3G and it has WiFi also. I really like it! The main disadvantage is that it's in black and white rather than color but that's ok for reading. You won't need the 3G if you have a network at home to pick up WiFi. I like the touchscreen but 3 members of my family have the navigation key one for $79 and they love them. The touchscreen is useful if you will be playing games on it.
