I assume it's possible, but for some reason can't find ANYTHING with Google on the subject, every "how to" is to do with a MBPro, not the Air. I have someone coming to stay for a couple of weeks, and when they get here we'll pick up a new MBAir, will they be able to plug into my 27" Apple displays and external keyboards? Or will they have to use their MBAir display while working here? Thanks in advance! PS... any number of dongles necessary is not an issue. I'm happy to buy them especially since that's something I can get ahead of time from Amazon if I know what I need to use.
