Dan Ackerman finally got his professional hands on a MacBook Air. One revelation in his review is the MacBook Air’s heat dissipation. It’s very, very effective. No heat to speak of, even though MBA vents hot air through grills located near its flat bottom. ThoughHere’s the review summary:

The good: Incredibly thin yet surprisingly sturdy; new trackpad gesture controls are very useful; remote optical drive makes living without a built-in drive much easier.

The bad: Very limited connectivity; slower than other MacBooks; SSD hard-drive option is ridiculously expensive and standard hard drive is small; battery is not user replaceable.

The bottom line: The design is revolutionary, but Apple’s MacBook Air will appeal to a smaller, more specialized audience than the standard MacBook, thanks to a stripped-down set of connections and features.
