I mean... part of the appeal is that nobody seems to have done it.  But you're right; this project is irrational as an attempt to build a laptop - and that was sort of some of the initial appeal.

But now I am genuinely curious about compatibility.  As far as I can tell the Board only has HDMI output - for audio and video.  I've never tried to run OS X on a machine that has no actual graphics card.  I'm not sure how GraphicsEnabler.kext will handle that.  I don't think I've ever used HDMI, actually.
