The Macbook Air is definitely the most interesting portable I've ever owned and it is by far the thinnest of them. Pros: This thing is thin and if you've never owned one you just can't understand how thin. It makes the Macbook Pro line look quite.. chunky. The weight is very nice and it feels like you could carry it anywhere with you. It really does feel like an ultraportable. The construction feels very solid to me and the unit seems sturdy compared to some units I've used (I'm looking at you Lenovo X60/X61 series!) while still being very stylish. The screen and speaker seem to be high quality. I've been watching some videos using VLC and the screen looks excellent compared with my Macbook Pro (which also looks excellent). The unit could use stereo speakers, but it isn't that big of a problem. Cons: The unit feels sluggish and slow at times. It is supposed to be an ultraportable, but you simply can't help comparing it to the Macbook line. I've been putting it through its paces and it benchmarks respectably, but you can simply feel the difference in load speeds when using it beside a 2008 (white) Macbook or similar. The charger could have a better design. Think retractable cord or similar handy ultraportable friendly charger design. One USB port, non-removable battery, other standard complaints. Enough said. Special Mention: Expresscard slot. This would be very handy to avoid the bulky usb modems for 3G data services. I'm not sure if it is possible to work one of these in given the form factor, but it would be a nice to have. --- I'm happy with the machine and I'll be using it until Apple releases a tablet or something else appropriate to replace it with like a faster Macbook Air. iPhone 3G and a Macbook Air, now all I need is tethering via Bluetooth and I'm set until Apple releases something else that is made of shinyium.
