3.15 mp camera
have a look at this
It looks very good, but if you are taking on a behemoth like Nokia, then why a 65k color screen?
Also only 400 mb on board memory.
lastly sony ericsson is known to have disappointing batteries. I use a nokia E61, 1500 mah of pure backup. The site has no mention of battery capacity. Hope the battery and screen improve by the time this hits the market!
