everyone that i know that has used the iPod touch hates it for the touch screen and for its size.
ive been on review sites recently and the k850 is said to be awful because of its touch sensitive buttons. they dont de-activate during a call so you have to hold the phone a metre away from your head when your speakin to some1.
ive found that the most helpful review site is
this one. the viewty seems to get a good write up and is a great looking phone.
