Im in the same boat.

Upgrade due but i dont know what i want.

Blackberry - Mate has one and its OK... nothing special though
Iphone - seems just like a fashion statement to have one?
HTC - Unknown,never used one so dunno what its like
X6 - Got an N96 just now, kinda want away from Nokias
N97 - As above and mate has one, wankston.
