Very interesting. I looked at this a while ago and could very well ending up getting one. The form factor looks a bit square though - presumably it wouldn't fit inside something like an N800 form factor?

What worries me most is wi-fi -- SDIO isn't much of an option the way I see it, I'm not aware of any good SDIO wi-fi cards out there. Compared to the N8x0 wi-fi they're rubbish. They break easily and the power saving mode support tend to be non-existent.
The other spec looks very good though. Could possibly have wished for twice the amount of RAM.
