Ingredients for a new Amiga:
1 off-the-shelf PPC motherboard;
1 out-of-date OS programmed by a firm which has previously released nothing but ports of other companies' open-source software;
1 hardware lock-in to prevent the OS running on other motherboards;
1 sticky Amiga label
Mix all of the ingredients, add a few lawsuits and an incompetent parent company, and bingo! one overpriced computer to sell to people who should really know better.
