I have pretty much decided on buying a 13" MBP for University. I think I will want the i7 as I will be running Engineering apps via bootcamp. I am in Canada, so the 13" i7 is $1449. The refurb store offers it for $1299. I know that I will get the App Store/iTunes Card with the new MBP, but I don't really consider that $100 in savings. So basically, the refurb is $150 savings for me. Is it worth it? I have read mixed stories, some claiming beautiful spotless machines, and others complaining about cosmetic damage. Also, is the i7 worthwhile or not?
