Mine (in black) arrived today as a Christmas present, and I agree, this thing is really pretty sweet. Enough spring to the keys to be very good for touch typing, but FAR lighter than my Apple Wireless Keyboard that I'd dragged around most recently. (That, plus the inCase Origami case for it, will go to my husband and his iPad Air.)
The fabric covering does take a little getting used to under your fingers, but it's not a problem in any way. The keys do have a nice snap to them, as mentioned, though the low profile of the keyboard means that there's not a deep feel to them as they are pressed. I'm typing this post with the Keys to Go on my lap; it's not too flimsy or flexible to do so. And unlike the Logitech Ultrathin, I can actually use this on my slippery dinette table without the keyboard sliding across the surface while typing. It's not super grippy, but enough to keep the keyboard in place for the most part.
My only complaint so far is the lack of an indicator for the caps lock key being on. Other than that, I'm well pleased!
