The Amiga "brand" is just that. It could be called Taco for all I care, since slapping "Amiga" on any old thing doesn't make it an Amiga. (Just like slapping Linux on any old thing doesn't turn it into an Aston Martin. *sigh* If only....)
The Minimig is cool, but I'm not really interested in another game system--UAE does that well enough. Netami is a nice idea. An ATX form factor replacement for the A1200 mainboard would be cool, but I guess it would make using busboards funky. Still, it could work well enough with accelerators or even have one on board.
