Well,
I don't have any technical knowledge to contribute to this project.
I'm just software geek and Linux enthusiast. I was so happy with my N900, but now it's about dead (losing GSM link). When Neo900 egerges, I will consider buying. It would be great to be able to use N900 camera -module as mentioned earlier in this thread. So if there would be "DIY" -option (add your own camera from n900) and price would be fair, I'll be ordering.
