Re: Buttons
That may be down to bad design. You either need enough buttons to do the job or a configurable interface (touchscreen usually) with optional buttons with straightforward functionality (I do not want a touchscreen volume control, thanks). Those devices trying to go the middle route and have two buttons for something where ten would be more useful, with patterns of press first button, then immediately press and hold second one, then tap first three times, are giving buttons a bad name that is not deserved.
