So just yesterday most of the keys on my 13" mid 2010 MB Pro (2.4GHz Core 2 Duo, 4GB Ram) all of a sudden stopped working. Instead of getting it fixed (which I'm guessing will cost a considerable amount of money for uppercase replacement) I'm thinking of getting a 2013 Macbook Air 11" baseline mostly cause I don't feel like spending much money right now. Just like my MBP, I'll be mainly using it for heavy browsing, Youtube, listening to music/watching movies, word processing and Photoshop (making gifs). Will the baseline spec model be adequate for the usage that I listed? Is the screen size comfortable enough? Also, how much difference in performance should I expect between my MBP and the 2013 MBA?
