I actually want a few physical buttons on my phone and tablet. Physical buttons to answer and disconnect a phone call, to mute the speaker (whenever ads popup on Spotify or YouTube say), to disable camera and microphone when you absolutely don't want to risk it (attending an office meeting while sitting on the toilet), etc. Without any dependency on screen being clean and registering touch properly or OS not being laggy at the wrong time.
