Hello, I brought my 2010 13 MBA to Korea for Summer Vacation, and my family members here in Korea are telling me to give my MBA to them and leave it here in Korea before I go back to the States. So I got permissions, and if I do give them my MBA, I will be getting the new 2011 i5 MBA when I get back to the states for free! So now, a couple of questions! 1. Has anyone upgraded from the 2010 model? Was there a significant performance difference? And how does the Intel graphics perform (3d) compared to the 320? 2. Has anyone regretted their upgrade? 3. Where did you buy it from? (Apple Online Store, Retail, MacMall, etc.) 4. I already have a 2010 i5 iMac back in the states, so when I get back to the states, should I get the 13 2011 MBA, or the 15 2011 MBP? Thank you!
