yes you can still install windows, word, excel etc on a mac. But then that defies the point of getting a mac. People only get macs to use software particular to a MAC. If your just using excel, word etc, then there is no point getting a MAC, your just wasting money. Some people get a MAC because they think they are better somehow, but theyre not, theyre just more expensive and more limited by MAC OS. They are less secure and just as/more prone to viruses, despite what moronic salespeople will tell you, I have had my fair share of experience with this. Macs are only for people in the graphic arts industry/music industry due to the software available, and even then similar alternatives exist for windows PC's too. So basically, unless there is some software that you MUST have a mac to use, that you want to use, then stay away from macs and save your money.
