The one and only Harmony I like -- the 670 -- is discontinued, so if ours breaks, we're screwed. I should have bought a dozen of them on EBay cheap when I had a chance. The others all have fatal flaws in terms of physical design, number of buttons, etc.

The Logitech software is an abomination, but once you get the Harmony set up properly, it's hard to beat. I've always thought there was a lot more room for innovation than there has actually been, but I guess there are enough network effects that it's hard to get established as a new player.
