I do typically lean nokia for 3 reasons, camera, audio, build quality.

No other phone maker has yet to match the n8's camera on a phone
I've owned and had lots of friends with other phones and nokias both internal and external has some of the best sound.
I never have to put a case on a nokia phone

That being said I have owned htc and samsung phones, always letting me down in at least sound and camera, neither broke on me

I almost forgot multitasking, I know this is OS, but only symbian, maemo and meego properly multitask. My android phone multitasking is a joke in comparison.
