I don't want to buy a separate GPS though and lug that around, so a stand-alone GPS app that works even if the phone is in airplane mode is helpful (doesn't have to be TomTom, there's free alternatives from what I understand though I haven't researched them).
So I think there is some reason to buy TomTom or a similar app.
EDIT: I did try war-driving neighbourhoods to find open Wifi to get data to use the maps, but that didn't work well at all for where I was.

Android gives turn by turn and you can cache an area for offline use. Not sure how large an area you can cache - haven't tried it out yet.
Bias warning - I have a Galaxy Nexus on JellyBean and I love it to death.
