Today Apple announced their BootCamp feature for Mac OS X, which allows Intel-based Macintoshes to install and boot Windows XP. Holy ska-moly! This is a huge move. They've even redesigned the Windows XP logo, creating an "X" out of the negative space. Nice!
I sure hope that this portends virtualization in Leopard. Boy howdy, do I!
[UPDATE (4/6/2006): BootCamp's nice and all, but that virtualization I mentioned is available today for $50! The future, as they say, is now.]
