So right now I have a Early 2011 base model macbook pro 13.3" and i'm interested in a base model 2013 macbook air 11". I can sell mine and upgrade to the macbook air for $140. I prefer the portability of the macbook air but I am a bit concerned in the reduction in screen size. Anyone find the size difference to small to work with (basic tasks-web, mail, iTunes, word processing, etc) I figure for a $140 I am getting a new air that will have applecare and my current one is 2 years old now as well. Looking for some feedback from others who have made a transition from a 13" macbook pro to a 11" macbook air.
