I think the 'keyboard all-in-1' methahore is severely dated. Even Apple would never do it, their monitor and console in 1 is already bordering on the riducule.
But I'd love a stylish, fanless, highly integrated unit, with 1 AGP and (at least) 1 PCI slot and enough room to add RAM. And CHEAP, because the current A1s are far too expensive. Also, no legacy interface nonsense (like serial, parallel port). It should look a bit like the Shuttles, but using a special case designed for Amiga. Even better if its an official supported Amiga computer. Then, it would have the Amiga logo and be sold with a keyboard with Amiga keys.
