Positives:
Slim & Light
Music Buttons
3.5mm headphone jack
can take up to 4gb microSD card

Bad:
Slim phone not good for SMS messaging
It's only really nice if you use it as basic ipod & basic phone
Bad Camera
Battery life not great because slim

conclusion:
if you really want mp3 + phone get this but... you won't have that great battery life & the speaker isn't that great

You better off buying Nokia 6233 + Ipod
