I personally don't need color buttons but if they are usefully for a large percentage of the target market they should be on the remote.
Logitech/Harmony has basically put out nearly the exact same remote with each model... some have color screens, recharge bases, buttons moved around/added/removed, etc but... each "new" model adds ZERO value since they all do the SAME THING!
This is why I bought the lowest priced version with a decent button layout 676.
The 'one' is no different... gives users nearly zero benefit over any other remote they make. Why don't all new Harmonys RF built-in now? What about z-wave (fast becoming the defacto standard for HA)?
Not that many other companies are better but at least two of the new Philips remotes have a jog wheel!
Harmony was a huge step forward, 5 years ago... they have 'played dead' since and maybe even gone backwards.
Shame on Logitech / Harmony!
Shame on people who are supporting a lack of innovation buy running out to "upgrade" when new model come out.
