These machines are almost impossible to operate without a remote. But remotes are not standardised; nor are the UIs the machines present. As a consequence, I become the only person that can efficiently operate my TV. And when I switch TVs, it takes me a month to learn how to drive it. The girlfriend doesn't have a chance.
Maybe I'm just slow on the uptake.
If TVs were cars, each brand of car would have different arrangements of controls; some would have a joystick for steering, some would have manual accelerator lever like a boat, some would have a horn operated by a foot-pedal, and they'd all have completely different gearstick locations for the different gears.
I need three different remotes to operate my TV: one for the TV, which I use only for switching inputs; one for the Sky STB; and one for my audio amplifier. I need all three to set up a viewing session. This is nuts, not least because none of these remotes is specific to the device they're paired with; each of these remotes has non-functional controls that are obviously meant for some other model, because they have no function or meaning with my model.
Disused remotes pile up in drifts in a cardboard box in my spare room.
Maybe in some distant future, the industry will come up with a standard for remote controls and user-interfaces, such that once you know one, you know them all, and so that any remote can be used to control any A/V device. This would drastically reduce the number of prefectly-good remote controls that end up in landfill.
I have a remote for my receiver and my TV, but I never ever touch them. The nice thing was that the only configuration required was to enable CEC on the TV and receiver. Everything else just worked.
Eventually I believe it will evolve into something more functional.
