Agreed on your points as well.
The Harmony One battery life has been poor, at least from the perspective that even when not getting 'heavy use' I need to cradle it otherwise in about 24 hours its under 50%. The buttons have been pretty good the past couple of years, but they are starting to feel less 'clicky' and more 'sticky'. Maybe I have a touch touch?
The touchscreen for me is ok but it fails the (please take no offense) Mother-in-Law/Father-in-Law test.
In my observation the casual HTPC user does not use the screen/ & never goes to 'next page'.

FWIW, using iMon to control WIn 8.1 WMC.
