Looking to get my son a new MBP 13" for his B-Day, but just not sure which one I want to buy him. I am looking at the three models in the Refurb section: 2.3 i5 2.4 i5 2.7 i7 I know there are minor differences but is it worth it to spend a few hundred more for the 2.7 or just get one of the other units, 2.3 or 2.4? I am looking for advice on those who own either. I have the 2011 Mini with the 2.3 i5 and 8GB ram, it works fine, but this one has to last him thru college, also I am planning on a Intel 320 300GB SSD as his main drive, and a external for backups. It will be used for Browsing, email, some games that run on Mac OSX, nothing fancy, and all the basic stuff he does now with his 13" MBP 2.4 I am familiar with the CPU options on the 2011 Models, just wondering if there is a big enough diff between the i5 2.3, and 2.4 compared to the i7 2.7 otherwise he could go with the new 2.4 and get his student discount for $1,100.00 plus on new, he gets the discount on Apple Care? How are the 2.7 i7 CPU's?
