hi! I currently own a mid-2012 i7 MacBook Pro (unibody but not retina) with 16 gb of ram and a 7200 rpm hd. No ssd. The processor was top of of the range back when I bought it. How would the current 13" MacBook Air base model compare in terms of performance ? I don't do much heavy-duty processing but desperately wanted a matte display and this is the one model where this was a bto option. I'm now beginning to feel that I need a speed bump in everyday tasks and I'm contemplating a Macbook Air despite the inferior display. Any thoughts are welcome. Thank you!
