I have to say that I am with Vancouver on the 1000. This thing is a heaping pile. I have all of components in a rack in a closet in the outside hallway, so I NEEDED the RF. Needless to say that it doesn't work, so I need to keep the rack pulled all the way out to work.
The 1100 is pretty sleek looking though, but I am going to consider the MX3000 from Universal. It has a similar UI, and from what I have heard from owners, it is leaps and bounds better than the UI that Logitech implements.
