I am a home user of my current gray haired 15 in 2010 MBP. I do almost exclusively simple tasks like web, email, photos, word processing, spreadsheets. I rarely edit movies into DVDs anymore. It seems that there will likely be a 12 inch retina MBA in the next few months as well as as a refreshed retina MBP. I have searched this forum to try to choose between these 2. I could probably do just fine with the rMBA but I am worried about not having any ports. Portability is no issue. Cheaper price for rMBA is nice but not a deal breaker. What would you advise your granny to do?
