W810i is a good phone - W950i is great for music (4G memory) but wont fit in your pocket easily - also not great as a phone.
I used to have a K750i which i think was the easiest, most usable phone Ive ever owned, with a great camera, MP3 player - looked great too - old now, but I might get another one.
Nokia N95 looks the business - and nice and small.
At the moment Im using the Blackberry Pearl - Looks great - not easy to use as a phone though.
Yeah, Id say the W810i
