What do you think of the Macbook Air keyboard?

I'm a new Mac user, and I jumped ship from my HP laptop. Bulkiness was the reason I moved to the Macbook Air.

One thing I missed from my HP laptop, though, is its great keyboard that has a lot of travel.

I considered getting ultrabooks, but the keyboard on the Zenbook was deemed too shallow and although the one on the Folio 13 shines, it's too thick.

So I went with the Air. However, after prolonged used, the keyboard actually felt quite shallow. I would say it is still better than those in the Windows ultrabooks, but it is still shallow enough to make typing a little burdensome.

So, Macbook Air owners, do you feel the same thing? And do you ever consider buying a bluetooth keyboard?
