I also received my new N800 and I agree with the review: the new Nokia looks nicer, the applications are snappier and generally better designed, the screen is noticeably better. The new keys are different, but not worse.

Comparing the 770 and the N800, the 770 looks like a beta version (which it probably indeed was) and the N800 the final product.

I love some changes:
-2 (TWO) cards, and full size, yes!
-a microphone plug (in the headphone plug), and we still have a built-in mic
-BT keyboards are supported
(I complained about all of the above on the 770...)

A welcome improvement are the stereo headphones and the built-in stand, both are actually quite good.

The webcam is only so-so: very noisy and no correct white balance. Maybe a new soft will improve the last part.

Google video play, but not well at all (very jerky).

I managed to install all the soft from the 770 that I needed with only minimal fiddling.



To answer the question about BT keyboard: you can use the keyboard, other BT connections and wifi simultaneously (you already could on the 770).
