About 3 weeks ago my main computer (PC) broke, and since then i've been using my MB 13'' late 2007 as the main computer. I need a new computer, and I've been thinking about an iMac. However, a MB Pro seems a very good option, since: - I'd use it at work (instead of my 4 years old PC). I go there by car everyday, so the weight is not a problem. - I'm leaving my home (currently living with my parents) in 6-8 months, so a laptop would be more "portable" than the huge 27'' imac. So: what do you think about the 17'' mb? some people have told me to aim for the 13'' and buy a external screen, but I don't like it very much.
