Ok guys I'm in a bit of a quandary. Hope someone can shed some light or has been in a similar situation. I'm a musician/producer/studio owner.. and I'm running a pretty powerful machine in the studio. Audio, samples, VSTs, and even heavy duty video editting - I've yet to encounter anything I throw at the studio machine that so much as makes it hiccup. For my main use computer (which entails normal stuff: iTunes, web browsing, Youtube (1080p preferable when possible, downloading movies (legally of course, but again either in 720/1080) and Airplaying them to a AppleTV2, Netflix, email, messaging, and light document stuff). No gaming, no actual recording/production work (other then the occasional idea in GB), no video editting. This is a 15inch 2013 Retina Macbook Pro I7 2.2ghz with 8gigs of Ram (4 that I upped to 8 myself). 250gb SSD.. but I store a lot of data in the cloud and I'm super privacy conscious (PGP, Filevault, ZeroKnowledge Cloud backups). My problem is this: I'm starting to feel like the the rMBP is too big of a of a machine. I occasionally travel, but there are long periods when I dont. I do enjoy the 15 inch screen and retina display... but I remember owning Macbooks (and even my studio iMac is non retina) and thinking the machines had great resolution. I'm seriously considering selling my rMBP and using the cash towards getting a 13inch MBA. Will I notice the difference going from Retina to Non Retina? Will I notice a huge size shift going from 15-inch to 13? (most movies/shows I Airplay anyways). Will I notice any significant slowdown in overall computing? Now that it's established theres no retina macbook air.. I feel like I'm stuck between a rock and a hard place. I dont want to "obsolete" myself and go from an i7 to an i5 (and possibly less RAM) for usability/resale reeasons.. (esp if a retina MBA comes out soon in a surprise), but I'm also getting annoyed with what I feel is a clunky laptop that's got more horsepower then I'm utilizing. Anyone been in my shoes? Moved from a retina MBP to an MBA and not really noticed a difference? And does 1080p content simply play at reduced (720p) rate on a MBA screen? Would appreciate any nudging one way or the other.. Thanks!
