yes! Im using it at 1680x1050 the highest possible. But do note that MacBook Air does not come with SDXC capability. Not sure why Apple decided to not put that on the MBA
I dont care about sd card - it is too slow... all I have to decide is - go portable (mb air) or go big screen (cmb 15)... or, go temporary (mb air - then sell when haswell is out) or go permanent (2-3 years solution - mb 15)
