I had the 880 and just replaced it with a Harmony One because the screen on my 880 was dying. I like the One much better. Feels great in your hand, the screen is much easier to read, the buttons are better and more logically laid out, etc. As others have said, the Harmony's are easy to set up and work great with their web based setup. When I bought the One, I just had to log into my Harmony account and go through the "replace remote" process and my new remote was working in no time.
