I've heard good things about Waze (though that's only been in the US so I don't know if it's a good map app for Italy). I liked Maps.me when I was in Iceland (though again I have no idea if it's any good in Italy).No, I mean YouTube is the only service I would find truly irreplaceable*. So great for music discovery, documentaries, tutorial/instructionals...
Yeah I know I'm being a hypocrite by not using Amazon or other stuff for their ethics, and then selling my soul to Google for knowledge, à la Doctor Faustus
*(I don't think I could easily do without Maps, actually...) (Jeesus I feel so filthy now)
