I've owned a Harmony 880 for 5+ years and have always been very happy with the way that it allows me to control my devices. Some of the buttons are starting to become less responsive and I'm itching to upgrade (sidegrade?) or make a switch. Before I buy a new remote, I'm going to try to take my existing 880 apart (have combed through that thread for tips on how to do this) to see if that satiates me for now. And if there were one thing I could change about the remote, I'd make the buttons a little more comfortable.
I'm pretty sure that I don't want the Harmony Touch because I like being able to feel where buttons are and don't want to necessarily look down at the remote to make a decision. So I'm basically down to either the 650 or the One. The major distinguishing factors that I can determine so far are the following:
Harmony One has rechargeable batteries w/ a cradle; 650 does not (standard AAs).
Harmony One can control up to 15 devices; 650 can control up to five.
Harmony One has a touch-screen; 650 does not.
Is there anything else that I'm missing? Obviously part of me wants to get the more advanced remote and go for the One, but for the price difference ($200+), I just don't know if the above are enough differentiator for me. I only have four devices (Samsung TV, Onkyo AVR, Comcast DVR, Xbox360) and don't know that I'll be adding anything, so the 5-limit on the 650 doesn't bother me. Even if I decide to get a Blu-Ray player instead of watching DVDs on the Xbox, that's still within the five. I can live w/ managing my own rechargable AA batteries vs the cradle. Does the touch screen on the One really add a lot of utility? The 880 works fine for me right now and controls all my devices the way I like. I feel like going to the 650 would be a similar user experience with perhaps a better button layout and more comfortable-feeling buttons. I'm trying to talk myself into a reason that I need the Harmony One, but can't figure out what it has in order to justify the price.
Note that this is for the main family room setup, so the simpler-looking 650 is also probably better for the wife and kids (is it more durable or does it just look that way?). If and when I take on finishing the basement, then I'll likely get something more geek-oriented for down there.
