Hm, if this can be done for a reasonable price, I'd be interested... in a replacement board. I've already got two 'broken' devices, so all I'd want is a board.

Heck, I'd be happy with a N900 board re-soldered with a better eMMC and more ram - CPU can be overvolted and OC'd up to 1GHZ well enough for me(It's been two years or so; I'm happy).

That being said, if you're going to the trouble of re-designing the board and doing a lot of work that way, I'd much prefer a /much/ faster CPU (OMAP 4?), and would pay more for it.
