i don't really go for the look of the phones but the functionality. w850i, being the newer phone, is obviously more powerful than 800. the thing is... sometimes, whether the phone is user-friendly and comfortable or not are not solely dependent on how advance it is. so i'm wondering is it as/more user friendly compares to w800? and is it worth the extra money to upgrade?
thanks in advance.
w850i

if i'm getting 850i, i'll go for the white one.
