I like avionics and ATMs where you see these. They're great for experienced users with relatively fixed functionality.
You can't tradeoff UI factors so easily, though. If you usually have 5 options, and found you have 6 somewhere-- you need to break up the section or add a page, etc. And if you add an option the user UI workflow completely changes.
While, with a touchscreen you could accept a smaller target for the least-used option, and adding a new target on a page doesn't change things too much for users (and is arguably more discoverable).
