Macs have enough support to be able to get just about any comon job done. PC's get enough support to get any job done.
OS4 and A1 get enough support to boot, and run an amiga emulator. For the price of a motherboard and OS you could get a new PC with an amiga emulator.
I predict OS 4 will be abandoned within a year of release as all parties go bankrupt or find another market of unloved faithfuls to milk out of hard earned money.
