So I've been debating for a while and I need some thoughts and opinions. I currently have a 2.66 GHz MBP 15" with 1 TB of storage. I've been debating on downgrading to get a 2011 MBA 13" with 128 GB or a 2012 MBA 11" with 64 GB.. Now, reason why I wanna sell my current MacBook Pro is because I'm tired of how heavy it is and the battery doesn't last even 3 hours. I don't do anything hardcore, I'm a basic user, iTunes, iLife, Web. But I have about 200 GB of music. What I was planning on doing was getting a thunderbolt drive and have all my files and music on there if I get a MacBook Air. But I'm not sure what one would be more worth it. The 2011 or the 2012. (read above) BTW I have a Craigslist buyer wanting to buy my MBP for $900 hence why I'm stuck between the two Airs. Anybody have any suggestions?
