I have to be able to run a strictly windows computer for my work, and I have a mac at home, and I was thinking about putting windows 7 on it. I already know how to do it, but I was wondering if any of you people who have done it, or even if you guys have just heard about it, if there are any major problems that windows will do to my mac. I was not sure that I wanted to "Taint" My mac with windows, seeing as windows was the reason that I switched to a mac, but I was wondering if it was bad for a mac to have it installed on it. Does it slow the Mac down at all? Does it leave a bunch of unneeded files on my computer even after I have deleted the windows partition? Thanks very much for the help.
