I didn't notice any claim that w2k was superior to xp. For myself, w2k is good enough and it doesn't have copy protection. I would certainly select a legitimate copy of xp without cp above w2k. I have several purchased copies of xp on various pc's but for some reason always end up on the one that has w2k.
I'm probably not the average user, at least in the general population, in that I frequently swap/add/remove parts from pc's and sometimes this entails reloading the os. The idea of being restricted in the usage of a legitimately purchased item grates. Having to deal with the cp is, at a minimum, inconvenient and can be a pita. Having to keep track of which cd has been installed on which pc is time consuming.
Don't know why I'm going on like this since, for the most part, I'm probably singing to the choir. I've just never expressed it before - so there it is. I guess I'm tired of being made to feel like a criminal when I'm not.
