Hello I am in the market to buy the windows 7 software so I can use bootcamp to launch Microsoft on my 2010 15' macbook pro. I know there are three different widows 7 (home, professional and ultimate). I need help on deciding which windows software is the right one for me. I am a college student and just like to do minor gaming. I just need help on deciding because I don't know what are the differences among the three. I tried talking to someone at bestbuy to help me out but the person didn't know what they were talking about.
