I've had it on 3 computers since its release. There were driver issues when it was brandnew, but that hasn't been an issue for more than a year. 1 of the laptops had the same issues installing sp1 that another poster mentioned, but that's also in the past. All in all, I like it and see no reason to use XP, I prefer Vista. I've also never had a problem with IE7, but I suppose that's personal preference, and a seperate issue from the OS. Also, Vista's power management features are much more powerful than XP's.
