As the title suggests, I'm considering upgrading my 13" 2011 Macbook Air (i5 entry level with 256 SSD and 4GB RAM) to the newer 2014 13" rMPB (entry level with either 8 or 16GB Ram and again 256 SSD) and am wondering if I'll see a significant difference in regards to the overall speed and performance. I use this machine with normal use (Youtube, HD Video watching, email, web surfing etc - basically a couch and bed computer)? I don't play many games, but maybe I will given this new machine. I have an iMac for any of the more processor hog types of things (ripping Blu Rays, encoding, etc) Has anyone else made the same switch from a 2011 MBA to a 2014 rMBP and seen a significant increase in speed and performance. Don't get me wrong - my 2011 MBA is nice and still has some pep left in her. I'm just trying to justify in my mind if it's worth making the switch (and spending the money). If the increase is really unnoticeable then I may wait it out. I do however like the thought of going to a retina screen. When I use my friends iPad2, I hate the quality of the display and can't wait to get back to my Retina iPad. If I do pull the trigger on the purchase, I will check out the current offerings of Refurbs of the same configuration, as it seems there are a lot of people on here who have great things to say about refurbs. Thanks!
