I went from using an in-dash touch screen nav to the 2011 RX remote touch. In the RX, the controller is positioned perfectly, where my right hand naturally falls right on it. Because of that, I find myself constantly fiddling with something on-screen, be it nav, audio, custom settings, etc, because the controller is so natural.
I like it a lot. When I get in my wife's TSX with the control wheel thing, I am still looking for the remote touch...
