I had the ultimate keyboard and it was nice on a desk, but in my lap while in bed it was flimsy and awkward. I returned it.
I didn't get the zagg folio, I got the Zagg Cover keyboard, and it's fantastic. It feels like a full sized keyboard and the screen is far enough away that my fingers didn't inadvertently touch it when typing numbers (which was a major complain against Logitech's scrunched keyboard layout).
Also the Zagg Cover let's me put it at whatever angle I want, which is handy.
Sorry - not exactly what you asked, but thought I'd chime in. Good luck!
