And that's the superficial stuff.
That's also weird/misinformed stuff to say the least:
> Backspace and delete?
The Air has a backspace key, and a forward delete can be achieved via Fn-backspace (on OSX at least)
> F keys?
Of course, 12 of them
> Mouse buttons?
Yes, two.
> Price?
Same price category as most other ultrabooks.
Is Fn-Backspace sub-optimal for forward deletion compared to a dedicated key? Sure. But it's there.
And that's the superficial stuff.
