Perhaps I should have given a little more background, I don't work for Dell or Logitech. I presently use an MX-500 (and have for couple of years) with my 990 (for a couple of months) and am very happy with it. I really like the MX-500 and don't NEED to try another remote. I just WANTED to play with something different. The Harmony remotes have interested me for a while, but the MX-500 just works so well. My only complaint with the MX-500 is that the "5" key should feel a little different from the rest of the keys to make it easier to find your position on the number pad.
Lonny, I'm glad to hear that yours works well and you really like it. Hopefully it'll work out the same for me.
Jeff
