If this holds true, for virutalization it looks like it will be a third party game, with Parallels first to market. LInk: I had a talk with Phil Schiller at the opening of the 5th Avenue Apple Store, and I asked him the question, will Apple include a virtualization solution in [the next version of Mac OS X] Leopard. He said absolutely not, the R&D would be prohibitive and were not going to do it. Our solution is dual boot. When I saw Parallels come out, I thought Apple would dis it, but this page suggests that Apple will actively support it.
I wouldn't get too carried away. They also said the iPod would not do video, PPC was better than Intel, etc, etc. Besides, no doubt Phil was talking about it from the perspective of having to develop their own VM solution from the top down. There's already a working solution on the market, if you see what I mean.
Apple is promoting Parallels solution on their own page, but I'm not sure if that means anything in the next 12 months...
