I have a MBA 13" 2013 and can get a new MBP 13" 2015 on discount. Love the MBA as its snappy, got long lasting battery life and I have never heard the fan (even if I put my ear to the chassi). I'm basically only looking for upgrade for screen estate (plan to run the MBP with 1680x1050 or 1920x1200) and a little better IGPU performance (only playing hearthstone). Is now a good time to buy? Or will the resolution do that I get less performance than my MBA? Do you think the MBP will be redesigned when the skylake version get released?
