I'm not in either. Actually, I was worrying about what to do if I suddenly receive it. Probably, I should not submit it in the first place. It would mean that I have to buy N810. I'm quite happy with my N800 and I would rather skip N810 model. The only attracting thing is a builtin GPS. But there are other things I do not like: external design, slider keyboard, micro-SD. Another problem is the infamous online store. I have bad experience with it when trying to buy GPS device. After three days of phone calls, where I was required to call them, answering to "verification" questions, finally they required American Express to verify me as well, I've canceled order and ordered GPS quickly, without any "verifications" and 50$ less in another store.

About the project I was planing to do on N810 (it was application for GPS photo-tagging), I've decided to buy Sony's specialized device instead. Funny, it will cost me less, then N810 with discount.
