How do you know that nobody you know uses Google maps? I'm assuming you know at least a few people who own smartphones and who you do not often travel with; have you asked them whether they use Google maps?
FWIW, the first thing I did when I first bought an iPhone was move Maps onto the taskbar - replacing Mail - since I used Maps more than any other phone feature.
Interesting. I was thinking the same thing. Everytime I decide to depend on ios4 maps (pre-debacle) for active usage (while driving), I end up getting lost because it was horribly offcourse. Other than offline direction search, I learnt not to depend on it. So technically, other than the Schadenfreude, I dont really have a lot of problem with ios6 maps since I can fireup maps.google.com for maps/directions
