If the price is right, a MiniITX sized Amiga would appeal to me, even if it were just and only OCS/ECS Amiga (Minimig). A littlebit more advanced (Jens' Clone-A MiniITX) would appeal more to me. I can surely do with some space-saving on my desk :-)
Imagine the space I could be saving dropping the 21" Mac monitor, the 9600/300 Mac, the A2000 and accessoires in favour of a MacMini with a MiniMig/Clone-A sitting on top of it, both hooked to a TFT monitor ;-)
