Maybe but it really is meant to be a 2nd machine, a true notebook in the sense of being just what you need to travel with and travel light. The desktop at home is your main machine or if you really need 15" or 17" size and power, then you do what people have done all along, carry the larger and slightly heavier machines. I think this machine really fits a perfect niche. Small, light, does what you need, surfing, writing, photos, etc, w/o the cumbersome aspects that a heaver machine brings.
As far as the port, get a pocket usb hub, those things are tiny, really my wife has one the size of a compact and it is 5 yrs old. I'm sure there are some pretty sleek ones out there. Better yet get one of those usb keypads that have two ports on them. Then you get a keypad and a couple ports. How much do you really need to hook up to this, especially at one time..
Forgot about a hub, I didn't realize that they have gotten so small. With the lack of a ethernet port i'll have to use an adapter for high speed at home (I' dont mind though, having another wire where a wire normally is anyway doesnt bother me) but I'd like to be able to charge my iPod aswell.
All issues aside, I think Apple's bringing back the innovation that they used to have back in the late 90s to the early 2000s. The Macbook Air is gorgeous.
