Yes they do. End of story. Yuck! I'd rather use a stylus with my smartphone than a universal remote. And I wouldn't use a stylus. Universal remotes are attempting to fix a problem that shouldn't exist were Apple to have the power to pull the strings and do a TV right. You'd have a single elegant remote and a TV. That's it. If you can't understand that that is not better than a TV with a few leads and boxes (or even just 1) hanging off your TV and a universal remote with an input switcher, I can't help you. Is it an Apple experience you're interested in, correct?
There's no point in arguing this when, and I'm going to sound arrogant here, you just don't get it. You're a geek. Back in the world of Mom and Pop simplicity is everything. "Hon, do you remember back when we had to switch inputs on a universal remote to change which device you wanted to interact with?". "Yeah, that was stupid." "Imagine now we can do everything now with just one TV and a remote. Gone are the days of boxes and wires and clutter under the TV. Now you can simply hang your TV on the wall and away you go. And if something goes wrong we call Apple and they handle everything. It's great."
That's the dream. That'd be insanely great.
