I have an older iMac at home, but i have never owned a Macbook Air before. Both doctors at my clinic are very much into Apple products, so i had a chance to try a Macbook Air 11 inches for a few days and found it performs quite well. I went with the 13 inches, as i found the 11 inches screen too small, still i didn't really want a laptop too big to move around when i'm at work.
I'm very satisfied with the service as well, luckily the one i purchased was in store. I'll definitely shop here again!
