This is the setup I have and I've been very happy with it. My uses are mainly web browsing, skype, a few video's here and there. I also have Win7 Pro configured on here via bootcamp and it runs that quite well also, though I only run it if I have a windows only software that I need to use or if i'm troubleshooting a windows network
My only complaint so far is the wifi performance isn't as good as my PC laptops with an Intel based wifi controller. Basic internet browsing or even downloading is ok, but when I'm streaming video from my media server my MBA has somewhat frequent split second pauses and skipped frames where my other laptops (even ones with less powerful CPU and GPU) stream flawlessly.
is this is a common problem? the internet/wireless card problem? or just specific to your unit?
