I spoke too soon when I posted my last article on Longhorn, here is an interview with Jim Allchin, 'Windows Chief' (whatever that means). This article reveals even more information is revealed about the new OS, and system requirements.
No pricing information has been posted. I hope Microsoft doesn't screw up and charge an arm an a leg for it.
If you're like me, I can't see to get enough information on the subject. Inquiring minds want to know.
