rokr e2 isn't bad...i like the idea of just dealing with the SD card(i got a bunch at home)...but i think the w800i's battery life is better...
w800i talktime is 9hrs i think....while the rokr e2 has 4hrs...
standby times is 400hrs for the w800i and 200hrs for the rokr e2
but those are just estimates...
doesn anyone know the battery life of the w800i while the music is playing and the phone just on standby?
