A bit late in the game, as Logitech are abandoning their remote lineup. (Bit of a shame, as there doesn't seem to be any good alternatives for hard-button remotes).

I don't have experience with the Elite, or 1000 etc., and I would just as soon stay away from the models that are mostly touch screens. (If I wanted a touch screen remote, I would just use my phone). For me, the top models in my experience are the 900 or the Harmony One. The 900 is the Harmony One with RF extension, and those 4 color buttons. But I have added IR extenders for just a few bucks, so I can use the Harmony One easily, with components hidden inside of a/v cabinets.

Where the One has the advantage over the 900, is its buttons have a better tactile feel and click. That said, I prefer my AR "ARRS05G" remote over both of the Harmony's, because it has a much better tactile button feel, layout and design. But it's not a touchscreen remote; more like a classier Cinema 7.
