Another vote for the N73 here aswell - got it last month and it's been really good so far
Spent a year with the N70, and I wasn't too into it I must admit. It was slow to do stuff, and everything was a roundabout kinda way of finding stuff, enterng details etc...
The N73 is almost identical to the N70, in terms of set up, menu's etc, but it's less "round about" and much faster. Still a bit slow to "boot up" when you turn it on, but for getting to messages, contacts, etc it's a lot faster than my N70...
Only thing is, it doesn't have a proper hard LCD cover/screen, and if you press it, or even wipe it too hard, it "smears" the LCD, like when you prod a TFT screen, cept it takes a good few seconds to wear off... Not too sure how long that screen will last, as it isn't as rugged as the N70 was....
Camera is shite tho

Good for taking pics to show on your phone or send to someone, but horrendous when put on a PC at full, or even half, size

Shame really as it's a 3.2 mp camera with Carl Ziess lens
