Put me down for a Harmony One RF. Also have an 890 and the operation is great. The paint has scraped off the much used rocker switches and it looks grotty, but it does work. Having the gear behind closed doors is essential.
So, like others in the forum, zero chance I will buy the current Harmony One or recommend it or the current 890. But once a ZWave or Bluetooth or something comes out, I'll be back for me and all of those who depend upon me for advice.
