Hi everyone, I currently have the mid-2011 MBA w/ 1.7 GHz Intel Core i5, 4 GB ram, 128 SSD. I'd like to know if it's worth the $300 upgrade to get a mid-2013 MBA? I mainly use my MBA for surfing the web, which I know isn't worth the upgrade. HOWEVER, I do occasional: Photoshop and Dreamweaver The 2011 MBA is already very good at this and rarely lags, if any. Just don't know if I want to get the new MBA just to stay on the latest MBA, or if it'll actually be an improvement for me for my intended use.
