Phones, as we know them today, entered market much later than consoles or PCs.

My point is that eventually we hit the ceiling of progress. PCs and consoles hit their peak 20 years ago while phones did 10 years ago. Things haven't changed in a while for both of them and it doesn't feel so far that there will be major progress any time soon.

Not in terms of navigating a city, which have had universal coverage since the flip phone days.

Also, just an FYI: GPS has had global coverage since the 1970s and doesn't require a cell signal at all.

Smart phone advancements have been incremental since they were released, very little had changed in terms of basic functionality. The biggest difference is that you can listen to music while your getting navigated now.
