I LOVE my E60. I couldn't care less about camera (unless it is as good as standalone camera), 850 band (don't need it on T-mobile), qwerty (don't need it, and it affects the size of the phone) or what type of memory it uses (i don't understand why is this important, unless you use same memory card for multiple devices and you need compatibility). However i do care about screen resolution (E60>E50,E61), wi-fi (E60-yes,E50-no), landscape mode(E60-yes,E50-no), size(E60E70) and price(E60
