In the first place vivaz touch is not good. made me sick of it cos i used it after a iphone. It's resistive touch. go for capacitive touchscreen.
And the screen gets scratches easily. And also the metal color corners get chips easily. simply the phone looks shit after little time if not kept in pouch always. furthermore the screen is 3.2 yes. but thats diagonally. truly the screen is narrow and long.
camera is ok but htc 5mp cams are far better. I've used htc hd mini and wildfire too...superb cam, and touch is better than iphone(truly)
best sony ericsson camera came with c905 (now too old). I didn't buy any new ones for about 6 months now. I always bought from ebay.co.uk but you have to be very careful. i've bought many smart phones, used a little and sold.
My advise is a blackberry with 3g. classy, and good.
