Well nearly – Apple have officially released beta software (Boot Camp) to let you install XP on Intel based macs. Not that you couldn’t do it already, but an official Apple solution is going to be a whole lot more reassuring to the majority of consumers and becomes (IMHO) another incentive to invest in an Apple product.
I couldn’t help but be amused by their riff on the Windows Logo, and some of the none too subtle critiques of the whole Windows experience; for example: “EFI and BIOS – Macs use an ultra-modern industry standard technology called EFI to handle booting. Sadly, Windows XP, and even the upcoming Vista, are stuck in the 1980s with old-fashioned BIOS. But with Boot Camp, the Mac can operate smoothly in both centuries.”
