So I have a 15 MBP C2D 2.66 with an intel SSD (80 GB). I'm sick of it's size. I definitely want to sell it for something more portable. I mainly use my Mac for web browsing, office, iTunes, and some HTML work. The main thing is that I want something portable for around the house and when I take it to school. I want to know if I'm better off taking my SSD and putting it in 13" MBP or just selling the SSD and getting a MBA 13 1.86 128 GB 4 GB of ram. I just want to get some peoples take on weather the smaller size is worth the trade off in performance. All advise is appreciated. Thanks Macrumors Forum!
