is it worth it or not???
If your computer is 100% legal, why bother?
Unless the calling home is something you can't live with.
I personally don't care about the occasional verification.
I have a 100% legal $200 Retail Copy of XP Home SP2 that I ordered online and I DO care - I care very much that anyone would load spyware like this onto my PC. I do not allow Microsoft to "update" my PC. Do I trust Microsoft? Not the tiniest bit - the CEOs are dishonest and are behaving like thugs, strong-arming users, vendors, banks, the ISO - and those are just the ones I know about. Microsoft is the main spyware vendor FROM WHOM I want to be protected.
