Slide Show: The MacBook Air in Perspective

The MacBook Air's graceful contours, so visible both in the first slide and here, come at a price: The unit lacks a competitive complement of inputs. The Air's sole ports--headphone, proprietary video out, and USB--are tucked away beneath a flip-open door. And "tucked away" is the operative phrase: Because the edges of the Air taper off, the ports are inset beneath the tapered edge, which may make it difficult to see where you're inserting your USB drive (assuming your drive's design doesn't interfere with the Air's surface). The unit also has integrated 802.11n wireless, a Webcam, and a mono speaker.
