I've got a 2008 Mac Pro, an iPad 3, and MBA rev B. I plan to buy 64GB runcore for $100 So basically I use my MBA when I know I will be browsing flash websites. I also on very few occasions use it for live tethering to my camera. So it's a very limited role. In the future I plan on buying a 13or 15" MBP once they get upgraded to the retina and ultrabook form factor. This will get an updated role of culling LR photos. I'm in no hurry to buy.
