Hello! So I'm starting to get ready to upgrade my system. I've been eyeing the MacBook Air for some time now as I feel my current MacBook Pro just is too bulky and heavy. I'm a bit curious how the latest fully loaded MacBook Air 13" i7 (and maybe a future Broadwell update, if you'd care to speculate) copes against my MacBook Pro with a i7 2.2GHz w 8GB ram from early 2011? Will it be a huge downgrade? As far as I understand the rMPB 13" is roughly the same in performance as the 13" Air. I really don't wanna be stuck with 15" for another three years, even though the retina is much lighter and compact compared to my current machine.
