(and giving them no tactile feedback whatsoever.)

That's funny, because my Apple keyboard seems to have this feature where you apply pressure to the little plastic buttons and this causes a tiny spring loaded plastic mechanism to compress and pop back into place in response to that pressure. It's almost as though I can tell when a button is being pressed and released by virtue of that physical up and down movement of the buttons alone. It seems like there's a word for that...

My first thought was, even if this were a viable contender for going up against Google... "Cuil it" doesn't quite roll off the tongue the way "Google it" does. If you want to compete with Google your first mission is to make your name a verb. Sounding equally unsatisfying are "Yahoo It", "MSN It", and "Live It".
