I think CarPlay is a test of this use. It's really similar, in that you connect your device to your car, and apps render a different view on a different form factor. You have a certification process so you know you have at least a chance of a good user experience. It's a subset of device functionality, instead of supporting more functionality.

If Apple invests in enhancing CarPlay, it might be a sign that they are scaling to a wider convergence market. If they don't invest or abandon it, then maybe convergence won't happen. They're famous for saying they're not working on projects that they are actually working on, so we have to read between the lines.

After upgrading from an iPhone 6 to an iPhone XR, I've been thinking how close the latest gen devices are to traditional computers anyway. The configuration/settings and features are so far beyond the first gen devices that I think convergence will happen, nobody knows what it will look like yet.

I don't disagree with you, but I'd like to point out that iOS apps have long been able to render a view on a television (via an AppleTV) while also rendering a different view on the device screen. This has been possible for at least 4 or 5 years.

There have been a few party game apps that allow a person to drive the game on their device while the other participants see what is on the TV. I don't think it ever really caught on; perhaps partly because AppleTV was a niche product way back when and partly because it didn't get much advertising.

I think the difference in what the PP was saying is that with CarPlay you can interact with the program while with external video you can only watch.
