Symbian phone...but which

Hello everyone,

i'm new and i do need help!!!

I want to buy a new phone and i already focused on three.

sony ericsson w950, p990 and m600...but which one.

there is a lot of information on these phones on the web...but i can't decide...

so, i want to have an touchscreen smartphone, a cam is not importend, i want to have a good music and video player, use an office application from time to time, it does have to have a qwerty though there is a qwerty on the touchscreen...
what about the stand by time? which one of them is the best???

hope someone can help me make my decission???

thanks

cielo
