I guess I've owned this laptop for a couple of years now. It's been hands down the best laptop or computer I've ever owned. Not a single issue with it and I'm kind of rough with it. I also have an iMac but I rarely use it, I find myself using the MBA 95% of the time so I've decided to sell the iMac and was thinking about maybe upgrading the MBA. I've got a Mid 2013, 1.3ghz i5, 4 gig RAM, intel HD 5000 graphics card. I'm into photography and do a fair bit of Photoshop. This is really the only time that the laptop sometimes feels sluggish. Would I noticed mush of a performance increase with the current generation MBA over my current laptop?
