This so very much. Remote libraries on iPhoto are so awful it hurts. And every so often it opens into some new library it just made up, I don't notice and load in a load of photos. Several weeks later I realise when the drive fills up. Ditto for iTunes - but iTunes is worse as it shows the thumb nails of the missing content and fools you into transferring files even though they are going local, not remote like they are supposed to. If remote storage with default apps was solved by Apple (or even just made better) I'd be considerably happier with the Air choice.
