I'm eventually going to write a longer review, but here's my take on the N800 after two weeks.

- battery life is amazing. When the screen dims, the N800 is still on the net, and gets several days in this "standby" mode. I was running GAIM on my N800 and hearing chimes as my friends signed in and out over the course of two days. I've never seen power conservation + wireless connectivity done so well. A big thumbs up to the Nokia team.

- browser is very good. I was able to use it on nearly all of my regular web sites. Youtube being one of the few exceptions.

- the user interface, hardware and software, is OK but could use work. I'd like the four-way pad to be a bit raised, more like the 4-way pad on the Sony Mylo. Similarly, I'd like to see nav menus better designed for scrolling using this pad. Again, see the Sony Mylo's GUI (based on Trolltech's Qt, and one of the few places where the Mylo does it right, but that's another story).

- build quality - the N800 is solid but the buttons and battery door have enough side-to-side play in them to make the device feel a bit less substantial.

- Bundled apps - some are great (browser, chat), some are fair to poor (mail, RSS).

- handwriting recognition is awful. I think Nokia would do well to hide this feature until it's better implemented.

- the on-screen large touch keyboard is great. One suggestion - make it semi-transparent so I can use it with Google Talk while seeing the conversation underneath.

- bluetooth is OK, but the lack of support for audio and headsets really sets back this device for chat and VOIP.

- no hard case for a portable device like this is hard to understand. Nokia could be making a decent amount of money selling one, and it would make the device much more portable. As is, it's always slipping out of its sock sleeve in my bag, and it's just a matter of time before the screen gets gouged. (I'm aware I can hack a Nintendo DS bag, but I'm saying Nokia should have had their own for sale at launch).

- Hackability is excellent! Linux, many open source apps, combined with great developer support from Nokia puts this in a class by itself for developing handheld apps and customizing the device. Nokia's active support of several open source projects is first rate.
