the main things are the battery life and qwerty keyboard. i hear the battery life on the sidekick is better... but also can i just replace the SD card for my apps to move over? and can i still just install apps without getting them on the market? and is it still connected to facebook? I'm 24 and this is the first plan/phone I've bought myself, but now I'm considering giving up the phone for a better(?) one. also, it doesn't have a camera, right? how does the flashlight app work then? i know i should've posted this in the Sidekick forum... or the mytouch forum... but still.
