Just torn if I should get the Macbook pro 13 inch, with a 128 GB SSD, or if I should just get the Air. I really want a SSD since I hear how fast it is, and memory isn't an issue since I have a 21 inch iMac to store things. So, what's the better choice? The 15 inch pro is too expensive, so I am limited to the 13 inch size. I like the Air's form factor, but will the faster i5 processor of the pro really make it more worthwhile than the Air? Also, I'm a little concerned with battery life. the Air seems to be a little wacky, but does the pro deliver a more consitent 7 hour battery life (or just, is it better than the Air?) Thanks in advance!
