I just got my new 13in MPB today. I really love it, but I feel like the Air would be better. I'm doing word processing, iTunes, and medium internet usage. I feel like I should've gone with Air.. I've been hearing people say the Air is much quicker than the MBP. I already have an iPad so, I'm stuck. Should I return my MBP and get an Air? I need to keep it for 3 years. Thanks.
