I'd like to see computer branded as Amiga, but be a multi-core, totally programmable piece of kit that could easily be turned into any number of computers. We already know about the FPGA stuff, so the concept is not too far off.
Emulation was "big" for the ST and Amiga in the 80's. Why not now, again? One box that could be a PC, Mac, Amiga, etc. with several partitions, running the latest OS's and switchable either through windows, a reboot or selectable upon startup. I'd love to see an early Startup screen that asks: "what computer shall I be today? lol
