If you are dual booting, and you would like your other OS to be mac os X, then go for the macbook pro.
My experience with apple products is that when they are good, they are very good. When they are bad, they are absolutely horrible. Now would be a good time to buy a brand new macbook pro. I would avoid anything that was a 'first' apple model (e.g. a revision 1 blue and white G3, a 1st generation imac, etc.) as these tend to be the most problematic.
