True, you can only upgrade a few (3-5) items in your computer before XP requires a re-authentication, but the internal counter is reset every 120 days, so unless you're a hardware upgrade nut like me, it's likely that very few users would ever even be affected by it, or even aware of it if not for all of the publicity. I've been following reports & reviews at tech sites & in magazines for a few weeks. The most significant thing in all the debate I've seen is how even reviewers & publications that are notorious for bashing microsoft with great relish at every oportunity (& boy, does MicroSoft give them plenty of oportunities!) are pretty much agreeing that this time MS has gotten it more right than ever before. The harshest thing i've seen apart from the authentication fuss & the (now moot) scandal over embedded links, is the rather catty statement that this is the OS that WIN95 should have been. A couple of good places to get useful, relatively non-technical info on XP are ZDTV's website (See link) and the Northern Light WIN-XP se (special edition) page. Personally I'm not buying the upgrade to XP for my computer, only because I'm replacing the computer shortly, & expect to get XP on the new one.
