I got my Air today. Bought on the 2nd, arrived on the 6th...this is by far the shortest wait time I've ever had for something bought online, especially bearing in mind I'm in Canada. In fact, I've waited far longer for items WITHIN Canada! I have to give kudos to Apple for getting their product out there quickly and easily.
Believe it or not, when I checked my tracking email and saw "out for delivery", I got a severe case of the fidgets! I couldn't sit still for several hours after that until it came, and I was looking out the windows and doors non-stop for the delivery truck. Although I haven't used it excessively yet, I agree with comments above about the light weight and easy handling. It's super-thin and easy to hold, and the display is crisp and clear. I look forward to putting the Air through its paces over the next few days.
