Apple MacBook Air

The Good :

Bright, clear display with wide viewing angle
Backlit, full-size keyboard
Multi-touch trackpad
Weighs only three pounds
Stunning design

The Bad

Battery can't be swapped and battery life doesn't match claims
Slow, small hard drive

External SuperDrive and USB-Ethernet adapter cost extra; each takes the only USB port and is incompatible with other Macs

Non-standard video port requires special adapters (included)

Final Word
MacBook Air is a pleasure both to behold and use. It's quick enough for web, email, office applications, watching movies, and wasting time on YouTube. It slows down if you push memory usage past its 2 GB of built-in RAM, when slow virtual memory on disk comes into play, and launching applications takes longer than on a MacBook or MacBook Pro with its slow disk. The Air will run Aperture, but without a full-strength graphics controller or a faster drive, MacBook Air lacks the horsepower needed for applications such as Final Cut Studio.
MacBook Air is neither a speedy, expandable "pro" laptop, nor an inexpensive, rugged "consumer" laptop. In light of the traditional Jobs product matrix, it's not entirely clear who the target buyer is, but we expect the Air to appeal to two groups of customers.
Business users who travel frequently will find the MacBook Air's three-pound weight and slim profile highly appealing. Its video port easily drives a projector; its spacious keyboard makes note-taking a breeze; and its bright, clear screen is highly usable. Saving two and a half pounds of weight over a 15" MacBook Pro may not sound like much, but if you carry a laptop everywhere, it's a noticeable difference. We think the MacBook Air will find a home as an "accessory" Mac in the business market, with an iMac on the desk and the MacBook Air in the bag. But MacBook Air's non-swappable battery is a gross oversight that may limit its appeal to frequent fliers.
We also expect the MacBook Air to appeal to well-heeled consumers who don't need stellar performance but who do value style (not to mention Air's superior display). Just $300 separates the black MacBook from the sleek MacBook Air.
Those who bought the 12" PowerBook a few years ago might consider the MacBook Air, if their storage and performance requirements are limited.
Although the MacBook Air has much to criticize — battery and hard drive foremost — its benefits are compelling. A bright, clear, full-size display and backlit keys make it .
usable without the squinting and crunched fingers that characterize most ultralights. It's so thin, and so light, that it slides into a bag and makes hardly a bulge; even with its power brick and video and USB-Ethernet adapters, it seems hardly to add any weight to the load.
And MacBook Air's industrial design is a stunning union of form and function. The curved bevels make it look even slimmer than it is, yet create a super-stiff chassis, which doesn't flex or bend, and make it easy to pick the computer up off a table one-handed. Its wedge profile makes typing easy, and it settles into the lap comfortably.
And the Air is lighter than any Mac laptop ever made before, including the legendary PowerBook Duo. Not since the black PowerBook G3 series have we used such a tactile machine; not since the PowerBook 500 series has an Apple laptop so enthralled us.
At the end of the day, the MacBook Air isn't about speed, features, or bang-for-the-buck. Its value is simply this: it's both beautiful and a pleasure to use.
