Amidelf: At this point your stuff sounds way too much like daydreaming.. People like me need a lot more tanglible projects before it's considered real and worth of support.
For quick comparision.. See
http://www.iti.fi/iti5200.phpIt's not a new Amiga nor has it never been intented to be one, but it is real existing hardware and it's having specs quite comparable to your dreams.
This demonstration/development board is about 10*10cm (4*4inch) is now available for evaluations and I belive it could be quite nice basis for portable/low-end Amigalike machine, *if* any of OS makers would be interested on making a port. Final board design could well be smaller, or contain some usefull additions. For example: this CPU has direct IDE/ATA interface in it.. it was not necessary on our design, but for making small (inexpesive) desktop system it would be quite usefull feature, also it's Ram controller has DDR-mode, at this board it's used on SDR...
