UX probably not as good in that case. I am thinking about how buggy my voice-remote is for the TV. 1/3 of the time it works, 1/3 of the time there is some lag before it starts working (and requires waiting for feedback i.e. the listening tone before I can speak) and 1/3 of the time it doesn't work at all (never hears me due to lag or booting up or whatever else).
