Regarding maps: is there an app that lets you save out Google Map info offline? I'd like to be able to type in a city and have it save all the data. I was thinking of having my setup just be a dumbphone plus a wifi-only tablet. The tablet would have utility apps, including this offline-map app. I'd just need it when I'm lost or need to find something nice to eat. It should also have Yelp data on it, and have the ability to update the map and Yelp data when I'm wifi connected. If I'm travelling to somewhere, I can preload the tablet with the new city info at home.
