What is the OEM version of Windows XP? http://www.newegg.com/Product/Product.asp?Item=N82E16837102059 I own a MacBook Pro but I need to install XP using Apple's Bootcamp system in order to run design and engineering software related to my degree. After searching on several sites, I have seen many, many versions of XP. A standard home addition bundle costs around $200. This "OEM" version costs $90. I've heard the OEM versions have reduced functionality but is it enough to run any software? Please help because I'm a little confused with so many versions of XP and varying price ranges.
