I recently got a N810 after having a 770 for two years. I did not move to N800 because it was too soon for a replacement and I had concerns about it being durable and pocket friendly. I love the hard case and general ruggedness of the 770.

I've had the N810 about 3 weeks and like it overall and will not be going back to the 770. The faster CPU and improved OS are great. I did not like the idea of the thumb board but actually use it quite a bit in terminal, maemopad, etc. I have played with the GPS and webcam and can see the potential for incorporating them. The light sensor and LED is nice. The softcase works well in conjunction with the screen lock for carrying in your pocket and provides decent protection. But this is not a rugged device.

I am a bit disappointed with the browser. It's great that it handles Flash but Opera on OS2006 does a better job of navigating web pages, i.e. fit width to screen, panning, and zooming.

Overall I am impressed with the N810 as a hardware device but feel like 0S2008 is half finished in terms of overall presentation and consumer friendliness. Of course the software will continue to evolve.
