One thing I appreciate is how much better maps have gotten for non-drivers: bike and pedestrian paths, public transport (especially live schedules, delays, alerts) and legitimately good directions generated for walking, biking and taking transport.

I believe that using wifi to improve localization on phones also happened within the last 19 years—quick Google found me an article from 2010 about how they started gathering data for this in 2007. I definitely remember this having a real improvement on how accurate my phone's location could be, which made using maps much nicer day-to-day.
