Getting very curious about Windows 7 as well … Although the £50 pre-order version doesn't come with the XP Mode, that's actually not too much of a handicap. I've gotten used to having 2 hard discs in my desktop, swapping between them for games & email. Could still do that with Windows 7, using the second hard disc for XP apps as before 🙂
And the RC is something I could test drive on the trashed apps drive after the climate model finishes (130ish hours to go)
