Ok a few questions, I"m going to be building a new computer and after calling newegg and microsoft from what I understand if I buy XP Media center now I can get Vista Home Premium Upgrade by just paying shipping and handling. But Upgrade requires a previous OS and you can't do a clean install, which from what I heard can cause problems. So what would be the best thing to do? Even if I wait, the full version of Vista may be too expensive, would it be possible my college may post it for download also?
