Anyone here using a MBA as their primary machine? I have a 34" LG 34UM95 headed my way, and have recently picked up an upper spec 15" MBP, but the total cost of that setup is in the $3000 range - meanwhile my 11" maxed MBA sits in a case waiting to be sold while return days tick away on the 15" MBP. It got me thinking though - could I make it work? My primary issue with the the MBA was the screen, but paired with the 34" monitor via thunderbolt that would be a solved problem. Is anyone here using a similar setup with their MBA as their primary machine? It's appealing to me, as it's basically my "cheap" option - but I'm also pretty curious about the limitations of such a setup. Is it viable for Xcode, Photoshop, and web design?
