I have looked at the 11" before and am worried it is too small, especially for reading course textbooks on Nook Study app. With edu pricing, the 11" with a i7 and 8GB RAM comes out $35 more than the 13" i5 with 8GB RAM. Unfortunately there is no i7 option on the lower end 13" and I don't really need drive space. I am replacing a unibody 2008 13" MacBook and I like the screen size, but want the upgrade mostly for weight. Not sure how much difference the .6 lbs will make from the 11" to the 13".
