Hi guys, Need to buy a new OS. My brother has Win 7 Ultimate 64bit version. I like Win 7 its quite cool. However, he got it very cheap and on sale from a friend. I really would like Ultmate if I can too lol, but I don't think its worth the prices offered online. So I'm toying between Win 7 Home and Professional, obviously 64bit versions. Some help in deciding between the two would be appreciated, and perhaps a good link where I can get the software cheaper. As a side thing...my brother is a University student....and should have access to student discounts for buying the software....is there anywhere that offers the full version? The other question is because my brother owns the full 64bit version of ultimate....could he use softwareforstudents to buy the upgrade pack and gift that to me? I don't think so but just want clarification please. I don't have another OS of windows tp upgrade from as I'm keeping my previous system intact for my parents. Thanks in advance.
