I have a classmate who has a barely used late 2011 13" MBP. Mine is a mid 2010. The deal is really good. The 2011 has an i5 (2.4GHz) as opposed to my C2D (2.4GHz). 1333MHz RAM instead of 1067MHz. SATA 3 instead of SATA 2 (my main want). 500GB instead of 250GB (although I may drop my new 250GB SSD in it). What do you think? I'd love to buy a new MBP, but these slight speed increases and the deal I can get may be able to keep the upgrade itch at bay...for a little while anyway.
