It's been ages since I've been here, but this project really perked my interrest. I really missed the Maemo community feeling. I didn't read the 88 pages before me (something I would have done in the past, but not anymore) so I don't know if this idea was already discucced, but it would be really nice to make the main-boards available (like a DIY kit version), so we could change the innards of a regular N900 to this upgraded HW.
(though our primary target is to provide ready-to-run complete devices, we will also offer an option for you to buy the GTA04-NeoNinehundred board only, instead of the complete Neo900 device, to upgrade any N900 you already may have)
