A very good phone with a few annoying traits.

I've been a Symbian fan for years so the N8 was a natural upgrade from my N97.
A lot has been written about the camera and it's all true - there is no better camera phone. The multimedia capabilities of the N8 are very strong, Dolby 5.1 surround, HDMI video out, 720p video recording, \"play via radio\" (the absolute killer feature now copied by others).
The N8 has a 3d graphics processor so gaming is very good, connect it to your telly with the AV lead and play racing games using the accelerometer as the steering - who needs a Playstation?
It has USB on the go too, you connect memory sticks, hard drives, keyboards and even a mouse!
So overall I think this is a phenominal technical achievement for Nokia, I love it -BUT now for the downside:
Battery life, can't call it more than adequate, you get through the day, just (I'm a heavy user so others may do better).
The on screen keyboard, it's all there - character preview, haptic feedback but they put the cursor forward and back keys either side of the space bar, so more often than not when going for you hit and then the cursor jumps to the begining of your text - this frustrates the hell out of me!
Those are the only two things I can think of to criticise, It's a wonderful device
