I fail to see how Microsoft have ruined the computer industry. If you remember PC's from way back when I'm sure you'll remember the headache of working with them. We worked on a game where the boss wouldn't fork out for Miles Sound Drivers (middleware) so we had to write a driver for every single sound card that was available. DirectX came along and (eventually) put an end to all that. Comparing Microsoft to the Amiga is not a fair comparison. The Amiga had the advantage of a consistant set of hardware, the PC hasn't. Until Microsoft came along with their OS and attempted to get some standards in the PC market it was all over the shop.
