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.
