This Apple Commercial Was Too Self-Congratulatory To Run

And coupled with the fact that in 1984 the Mac WAS all those things, unlike today.

While I agree with you, the Mac (also the Amiga, and in a broader sense, the personal computer) enabled a lot of new professions too: graphical designers, video producers, photographers, musicians, anyone relying on CAD (engineers, architects), etc. Suddenly, all those people had a powerful tool to work with at a more affordable price. I believe that's what Murray was referring to, and I would say they were successful at that.

I don't think so. You'll notice that at the 1:30 mark he's switched from using the remote to the mouse. The pointer/cursor interface, even 20 years later, just doesn't work well when you're aiming at a screen occupying a (relatively) smallish span of your field of vision from 8-20 feet away, potentially at an angle.

My guess is that speech removes the need for typing, and everything else is via a one button remote with a whole host of gesture "smarts". Imagine flicking your wrist up to scroll and you'll have the idea.
