I apologize in advance for this frequent question: I thinking about selling my 2012 air 256/8gb for a Pro 13" 500/4gb and upgrading the HDD to SSD immediatly. Will i notice a big performance gain over the Air? I love the resolution of the air but the base macbook pro (non-retina) still suffices with its 1280x900. I am just curious as to what kind of gains i can expect when i go to the Pro from the Air. Will Win7/Win8 work better with bootcamp/fusion? Side note: i do want to play some flight simulators. Flight gear installed on my air, but will not open, same with Norton anti virus. It just seems the Air is lagging with the 1.8 i5. Thoughts? Sorry for the poor grammar, had to type this quick!
