I have a MPB and iMac at home, and would use my MBP when on the couch, or out and about. My opinion, the invention of the iPad, tablet in general, has been the greatest tech invention in some time. Im not saying that it makes my MBP obsolete, but if Im not using certain OS based programs, I do not turn on my MBP. My Air is much more convenient for me than my MBP now, and has changed the way Im doing personal and business work forever. Just wanted to get thoughts of my opinion from others.
