Is the 11" too small?

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".

 

I have looked at them before, unfortunately as they are tabled and tethered, you don't get the real world sense of using one on your lap or seated at a desk. I am leaning towards a 13". Bummer the 8GB RAM is BTO, I'll have to order vs. pick one up.

 

Are BTOs that are store delivered, or BTOs in general returnable with the 2 week no penalty policy?

And I am fine having it come to me directly, what if any advantage other than convenience is there to store delivery?
