Migration issues with MBA from welcome screen!!! Does not finish keeps searching for information. Apple tech support advised to load OS on again. MBA gets lost loading OS ?? w' issue for no prompt for disc two! This leaves you with partial OS!!! Apple knows it is an problem now. MBA not as tight and tested as my other Apple products. Oh, how I wish they had fire wire option! I have returned and will wait for issue to settle down. Neat box too many potholes. Have a good time reaching the MBA tech team.
