Hello, I currently have a Fall 2009 Macbook Pro. Specs: -15.4" screen, 1440x900 -Dual Core 2 processor 2.8GHz -500 GB hard drive -8 GB RAM (upgraded from standard 4 GB) -OS X Lion installed In 2010, I got an iMac for the more heavy duty actions, such as streaming and converting video, projects, music, etc. As it stands now, I use my Macbook Pro for basically the internet, email, and Microsoft Office. I currently use only about 90 GB of that hard drive. I'm looking at the Macbook Air, the high end model (13.3" high end). If I were to sell my Macbook Pro for an Air, would that make sense? Do you think the change is worth it, especially since I no longer use the machine to its fullest potential? Thank you for your help.
