Hey, this is AMIGA people we talk about.
But yeah it will probably be more expensive than NanoITX, but it might be cheaper than a pc104-board.
Then there is also the powerconsumtion, essential in a pda. Ok, x86 isn´t good in that department but considering the advantages of 1.)not having to port AROS and 2.)using x86 UAE with JIT
But I will have a pocket AROS-machine some day.
My favorite homecomputers has always been Amigas and my favorite PDA Apple Newton. Now if they could be combined. :-P
