Like many others, my N800 has arrived after I was also one of the lucky few who got recommended for the get-an-N800-on-the-cheap developer programme.
Nice device, and a big improvement on the 770. It feels more sturdy, is much faster, and the UI feels more mature. It is nice to see that Nokia commissioned a second device – I assume the 770 sold reasonably well. I really do think Maemo is an awesome platform, and it is great to see it on another device.
Others have summarised the N800 pretty well, so I won’t bore you with that here, I just wanted to give my thumbs up to Nokia with it.
