I dont like any i bought an iphone

No doubts in my mind! Have just got a Nokia N81 8gb slider phone.

Usual Nokia quality plus much more:

Direct link to computer for transfering music/pictures/films etc.
8gb inbuilt memory.
Wi-fi enabled

And unlike the N95 the battery life is very good.

Very good all round phone with every extra you could imagine
