the underlying assumption here is that thin is more important than additional USB ports, ethernet port, dvd drive and removable battery. If you agree with that, then maybe this is the computer for you. But I still think Apple made a big mistake PERCEPTION-wise by not including an ethernet port and at least two USB ports. These are things that people use all the time and need on the road. If this were priced at $999, it would be fine but at $1799 it's a lot to ask of the customer to go out and buy an ethernet adapter, a superdrive and a USB hub just for some basic connectivity and features, don't you think? It's not about weight either since other manufacturers are able to squeeze a lot into a very small package. It's just about thinness, nothing else.
And then Apple calls it AIR, as if it has some kind of special wireless advantage, when in fact its wireless capabilities are the same as every other laptop out there. the only reason it's AIR is that all the other wired, and often needed, options are gone. Not very impressive in my mind.
I love it and want it because it's so beautifully designed, but it's really too much of a compromise even when I try really hard to justify it and convince myself that i could be satisfied with its limitations.
