I must admit it looks amazing. It is downright beautiful to be honest... but it is FAR from practical. Though I have not touched a Macbook Air as of yet, and I'm sure when I do I'll want one, but the fact is I cannot imagine spending 2 - 3 thousand bucks on something that doesn't have an Ethernet port.... Maybe if I lived in LA, Chicago, NY, etc... where open wifi might be the norm it would work but around here, in suburban Indy, it just isn't the norm. Don't get me wrong, I really like Apple, and probably wouldn't mind having one laying around, but not for that much money and that little (no pun intended) return.... Just my thoughts....
P.S. If there is one thing Steve Jobs is good at its presentation. He REALLY knows how to launch a product. Hats off to Apple for their effective and powerful communication strategies.
