Hi guys, I bought my MBP 13 in Jan, and am considering trade it, along with $380 cash, with a MBP 15 2.4g i5, which was purchased in Feb. Both Macs are in great condition. So I'm wondering if it worth the money for me? Mostly I use my mac to do some programming. I'd like a larger screen. But is the 2 inch difference significant? Thanks!
