This post brings out what I meant here, when I said that being able to play popular games on a Mac meant the end of Windows (for me, at least - probably for a lot of other people as well). It's summed up here:
Both Mac and Windows camps have been buzzing these past few days with news of Boot Camp. Apple’s Boot Camp is an essentially just an installer that includes Windows drivers and a basic partioner. BIOS support is included in a separate update. Note, this is beta software and Boot Camp isn’t even the final product name. But what is more telling I think, is that this is going to be intergrated into Mac OS X Leopard. As it stands now, it’s a one time thing. Apple obviously intends for Leopard and Windows to be run side by side, (not just Windows) and I’m going to outline the importance of this in the following article.
Boot Camp is cool, but it's half a loaf. Having to reboot in order to run a game is not enough. If Leopard ships with the ability to run Windows apps without having to leave OS X, then I'd say that Microsoft has a huge problem. I said awhile back that MS was busily painting itself into a corner with Vista, and that it was going to cost them. The response from a few people was "sure, but what's the alternative?" Well, I think that alternative is becoming clearer. I've been recommending the Mac as a saner alternative for non-technical people for awhile now; the only gap has been "what about all those Windows apps?". When that gap goes away, it's a whole new ballgame.
Apple has dropped a bomb on the entire industry, and it's only starting to become clear how big the explosion will get.
