I have two Harmony 880's but I just picked up a Harmony Smart Control that is going to retire one of them. I'm not done setting it up (have to route the IR blaster upstairs to my TV) but so far it seems really slick. Having a basic remote for those quick grab standard commands plus the ability to run the app on the phone and tablet is nifty.
