In a grander view:
Micro controlers are very popular in the hobiest market these days. Usually after a while the hobiest finds some reason to need bigger, better, faster. Moving up means something between a single processor with limited I/O functionality, and a full desktop, laptop, or hacking their palm pilot.
There is a nich market that is rapidly filling this hole. Full computers on a small board. What you got is a desktop computer with no slots, on a board smaller than a book. Video, serial, paralell, and usualy some spare IO.. maby instructions on point to point wiring an isa slot.
The problem here is that the more you get in a smaller package the more the cost. Prices start at about 200 or so and go up quickly the more functionality you add. Last time I checked IDE drives were not avail on a board for less then 200 in single quantities. Keep in mind, this is dos/linux only. 286-486 range with about 256k and maby 2 megs of flash.
With all the functionality added, options, and ease of use (A LOT of people remember programing on the C64/128) these boards might be a great alternative for small Kiosks, custom industrial automation where a bit of fancy graphics are nice, but a laptop is way too expensive and over powered. If marketed well (I.e not JUST to C64 hobiests, but to embeded systems designers as well) It could REALLY take off..
A micro ATX isnt all that large by the way. its about 10-12 inches square. Not to mention, if it sells well, smaller scale integration wouldnt be to difficult.
I work in a casino, and for anyone who has been to one, All those fancy video machines are "middle ground" systems. They even have sound chips that sound very much similar to SID. All but the very newest are 68xx based cpus, running about the same speeds.
This really isnt as far fetched as it sounds from a purely technical standpoint. Very usefull in the Embeded market. And 200 dollars is cheap for the power you get.
