Yes and no and it highly depends where you live. Here in Munich the S-Bahn trains typically go every 20 mins during the day and sometimes every 40 very early or late. So that's already a problem if you want to arrive for work and can't just start 30min earlier, the regional trains often go every hour as you mentioned. So yeah, if you live where there's a subway or a bus then the 10min thing works, but just a tiny bit on the outskirts with only the S-Bahn it often sucks. I was very glad when I moved from "need to take S-Bahn or bus to work, or to the subway" to "walk or bus to subway" neighborhood, even if it's roughly the same distance to the city center, and both decidedly IN the city, not the outskirts.
