laptops displaced desktops, but it's because they offer essentially the same benefits and experience, but with portability and convenience
But they didn't originally, and not for a long time, even though it was inevitable it would happen one day. I carried various laptops around for years before finally being able to buy one that was powerful enough to be my only development machine.
phones present huge barriers in terms of input, display, and ergonomics
Keyboards are available that are full-size, yet which take up no physical space - a laser projects an image of a keyboard onto any flat surface, and a camera figures out where you're typing.
Mini projectors are starting to come out, meaning you don't need any physical space for a good monitor either.
Combining these two, with a good handheld platform and two flat surfaces (e.g. a desk and a wall), I don't see any real barrier to making this happen.
