"Sadly, they don't seem to have been taken further."
Maybe they'd not be backwards-compatible with their existing OS. That clean slate is a problem for everyone who's got an existing product. Just like Unix, MS has a heritage extending back into the '70s.
The 70s/early 80s had a big advantage. There was new hardware without any OS. Although Bell labs were working with hardware that did have an OS that was nullified because they'd been working on an abandoned line of OS research, Multics, so they also had a clean slate. It's going to be hard for anyone to push themselves back to that position and then try to compete against existing platforms with existing app-stores, however flawed.
