As many already know, Apple introduced a new notebook to their lineup on Tuesday. The MacBook Air is a sub-portable, very thin and light, and fills a niche that Apple has not yet competed in. There has been a lot of text already on the unit, so I thought I would give both a quick overview and some links to other sites to make reading up on it a bit easier.
Overview
Thin thin thin, from .16-.76" (40-194mm) - it slopes to thinness on all edges to make it look even thinner than it is
Light, only 3 pounds (1.36kg)
13.3" LED backlit screen with 1280 x 800 resolution - nice widescreen display, same as the current MacBooks
1.6Ghz Intel Core 2 Duo processor - shrunk down specially for the Air
80gb 1.8" hard drive - same drive as in the iPod Classic
Full size keyboard - backlit with ambient sensor, too!
Large multi-touch trackpad - multi-touch gesturing a la iPhone, very interesting to see where this goes
802.11n wifi support
Bluetooth 2.0
Comes with Leopard and iLife '08 (as do all MacBooks)
$1899 CDN
The "uber-Air", 1.8Ghz with a 64gb SSD instead of a hard drive is available for $3248 CDN - ya, sure....;)
