Can anybody tell me what the battery life is of the new N800?
Nokia normally does a good job at that, so it probably won't be that different from the 770, but I'd like to know for sure.

Furthermore were is this new tablet made? I read that the prototype was made in Korea, is the final one also?

How is the stability? I hated the crashes of the 770, and I hope it is ironed out in the new OS.

What IS running on this OS? Internet Tablet 2007? Will it also be available for the Nokia 770? That would we helpful for me in order to test stability.
But Nokia doesn't have a very good track record when it comes to long term support, so I wouldn't at all be surprised if the new OS would be N800 only. THAT would suck, especially if they ended support and OS updates for the 770 from now on. That would also make me think twice about geting a N800. A product that has 14 months of support from Nokia is rather expensive at 400 euros.
But Nokia also does that with their Symbian phones. A lot of/most software that is developed for the latest S60 third edition does not work on second or first edition, and there is no update for the OS on the phones.
I really hope Nokia changes its ways on the Tablets.

So it pretty much comes down to the new OS. They should release the update for the 770. And after I installed it on the 770 and concluded that it is finally stable, than I'll buy a new N800 for myself and recommend all of my friend to get one as well.
