Against all odds I have decided to upgrade my old VAIO. Part of the upgrade includes dumping Vista (no worries I hadn't used the VAIO that much) and use W7 as the OS. While "googleing" for the cheapest 64 bit version, I noticed really good deals on ebay

W7 for $45 or so. Download only with activation key. First I thought it was fraud (still not really convinced) but there are quite a few offers from established sellers with good feedback. Has anybody got a clue if this is legal and whether your OS is a legal copy?
Thanks!
