MBA Users, Hope your lov'n your machine! How is the quality of the mic and video cam? when i chat w/ friend who uses a macbook, her internal mic is quite bad--i usually have her use an enternal mic. but since a mic jack isn't included in the macbook the quality of the internal mic becomes more important. how is it? also, is the cpu powerful enough to push skype high quality video. (i know about ichat but i need skype). thanks!
