If a company was to rehouse either the Commodore DTV or Minimig in a nicely designed keyboard unit then this I would buy.
However no company is planning on doing this on the sort of scale where the price drops to a low enough level to become a casual purchase. They did it with the NES chipset for third world countries, but I'm not interested in Nintendo stuff.
(have rooms full of Commodore computers already...last count 25 C64s of various flavours alone)
