that BLOWS. i use my normal battery all day, with several hours of use. and i have the extended battery if i ever feel the need to use it.( Samsung BJ1)
i havent used a PRE(obviously) but ive used the Palm centro, hated it, dont like Curves much, HTC suck, iPhone is nice when you get it figured out and learn to type on it, i like my Samsung(and cosseys new one) but the web broswer kind of sucks on it, and the display is small.
