I always thought the Suzanne project (same page), based on the A600 was cool. I was surprised that no one tried to make a laptop from a cd32. The motherboard should have been small enough and you got an EC020 to boot. Cutting a slot in the case would allow the SX32 expansion to fit (and possibly an 030 upgrade).
Oh well, with the original Amithlon and WinUAE, it would be easier to just buy a windoze laptop and emulate Amiga.
