> What makes it important for them to use Unix rather than something that works fine the way it is while maintaining some standard of UX? The concern is whether the device is a piece of paper or a television. A television can show much more complex images under the control of the average child, but it is purely for consumption. A piece of paper lets you display anything you can draw or you can turn it into a paper plane or do origami, but the realism of the resulting products is going to be much less, and they will be relatively static. An iPhone is, by design, a television. Unix systems are pieces of paper. Last time I used MacOS, it was a functional piece of paper and it worked as a television too, so there isn't really any dichotomy here. Any television could be built on top of a piece of paper and give you access to the base level too. The concern is that the television is winning out: even though Android and iOS are built from pieces of paper, their maintainers only bless television-like interfaces. Frankly, I believe a major part of this is because they're built on top of Unix like interfaces, which is based certain assumptions that they don't want to maintain. So I certainly wouldn't say Unix-like is the solution.
