After all the hype about the new MacBook Air releases last week, all the oohing and aahing over the engineering that slipped a significant amount of power and capability into such a tiny package, I was ready to be somewhat disappointed by the new 13.3-inch MacBook Air that arrived on my doorstep earlier this week. I've used every MacBook Air since it was originally released, and I still use an 18-month-old Air for hours and hours every day. What could impress me about the new one? As it turns out, plenty.
