So I will be getting my first MacBook pro once ML comes out and I was wondering what the average life span of a MacBook is Not counting physical damage ( dropping water etc) I have an old friends iMac from 2006 and at the begining of this year it went south. So that last 6 years. Granted it was not an intel imac so a lot of newer programs would not work on it. Firefox and chrome being 2 on a long list of programs. But is 6 years a good number for a new MacBook pro?
