Having an FGPA on there is a very clever idea, it adds flexibility to the design in a way that a prototyping area would but much cleaner. The one corner with all the PWM and other connectors is the most interesting part, I really wonder what kind of plans he's got with this but it goes way beyond 'just another laptop'.
If someone did a 'Bunnie Huang uses this' post I'd be all over it, the tool collection to create a design like this would be extremely interesting reading.
