What about developer support? The app store? How do these other tablets compare to it? How many other "app stores" are as profitable as Apple's?
That's 1 key difference with the iPad is the amount software you can get on it and the multitude of uses you can gain out of it.
It's not all about specs sometimes...

Apple could market the Apple 2 again as "new" and people would still buy it.

I like the Air for it's design, but spec wise it's underpowered and overpriced. Specially for the "high end" model 13".
