Should I purchase a MacBook air 13"? I currently have a 24" 2.66 core 2 duo iMac, a 16 gigabyte iPad and cannot decide between the MacBook Air or MacBook Pro. I am a high school student and can go as high as $1499. I would use the laptop for Photoshop, programming, video watching, ilife suite usage, abelton, Microsoft office. Since I am a student weight is an option. What is your opinion? (I would wait for the updated mbp )
