After many years and many laptops, I've finally determined that I ride the periphery in terms of size and function – I like them either really big, or really small. The middle-of-the-road 15-inch standard just isn't for me. Thus, the MacBook Air seemed to be the perfect answer to the lighter side of that spectrum. My 17-inch MacBook Pro easily takes care of the heavyweight end.

The Bottom Line Apple MacBook Air Apple, apple.com Very Good  8.5 criteria score weight Configuration 7 20% Ease-of-use 9 20% Portability 10 20% Battery life 8 15% Performance 8 15% Value 9 10% Cost: $2,028 as tested with 80GB PATA drive, 2GB of RAM, 1.8GHz Core 2 Duo CPU Platforms: Mac OS X, Windows XP/Vista Bottom Line: There's really nothing like the MacBook Air on the market today. It’s ultrathin, ultralight, and ultrasmall, yet provides solid performance and usability. There are sacrifices, to be sure, such as the single USB port and the lack of an internal optical drive, but they're minor when the Air's size and weight are taken into consideration. You might not choose the Air as your only computer, but as a traveling companion, it's simply stellar. About our Reviews and Scoring Methodology

Whether I'm in the mood for a light laptop or a heavy one, I'm never willing to compromise much on performance. Many people reacted to the MacBook Air announcement as though it were terribly underpowered, lacking options, and generally useless as a laptop, thin though it may be. This is of great concern to me, because I tend to push my computers to the breaking point and run them like that for hours on end.

Apart from performance, there are other considerations. The MacBook Air isn't designed to be a desktop replacement system, and it doesn't have desktop-like specs, unlike the MacBook Pro (see Tom Yager’s review, “The best notebook you can buy”) and other 2.4GHz-plus Core 2 Duo laptops on the market. Could I live without a bevy of ports and a DVD drive? Could I use the Air to do real work?

In order to find out, I bought one and used it to write this review. In many ways, the Air has caused me to rethink some of my preconceived notions about what I need from a computer (see my “Deep End” blog post on that topic). While it was very tempting to bite the bullet and get the 64GB SSD (solid state-disk), I opted to save $999 and get the 80GB 4,200-rpm PATA (Parallel ATA) drive, though I did spring for the 1.8GHz Core 2 Duo instead of the base model running at 1.6GHz.

"Laptop" as misnomer
It's unfair to classify the MacBook Air as a laptop. It's not, unless you're Mini Me. It's an ultraportable, along the lines of the Sony Vaio TZ, though it has a larger screen than the Vaio. It's also faster and cheaper.

The Air arrives in a box that seems way too small to hold a computer, and yes, it weighs nearly nothing. Several times already, I've thought that my courier bag was empty when in fact it's not. Even with the power cord and a few cables, the bag just looks empty. Though the MacBook Air is small and incredibly light, it's also surprisingly solid. It feels like one piece of metal, and even picking it up by one corner, there's no flexing at all. Now, I'm sure it wouldn't survive a trip down the stairs. But neither would most laptops. Then again, given the Air’s light weight, it might have a better chance than most. Either way, I’m not quite willing to run that test.
