How did you create heaven and earth without it?

I hope to use it for getting unlost, finding local POIs, a reference library, a music player, a scripture reader, a communicator, and a journal editor while on bike tours, and as a replacement for my current dumb phone and Zaurus the rest of the time. It's unclear now how good it will be for the first couple use cases, to my disappointment. How the map app situation shapes up in the next month will probably determine whether i get one.
