Currently there aren’t that many support docs up on the MacBook Air, but the ones that are are very informative. The articles on tips for using the Air’s new Migration Assistant and optimizing Airport performance while using Bluetooth offer information that would seem obvious for experienced Mac users, though helpful for new converts. The Remote Disk setup guide offers a small look into how Remote Disk works, helpful for people who have a Windows machine on hand (interestingly, the guide uses Vista for the Windows computer instead of XP)
Unfortunately, Apple has yet to add a dedicated MacBook Air support docs-section, so you’ll have to hunt down articles like these on your own, for now. But, despite that, it’s good that Apple is allowing soon-to-be Air owners to address some of the questions they may have beforehand.
