I’ve been using Here we go for years. I think it started as a Nokia project, that spun off to it’s own thing. I started using to conserve data. You download the map of your region when you have Wi-Fi, and it’s pretty low data load from there, directions and traffic updates mostly. I’ve been happy with it for a long time. I haven’t opened g-maps in ages. I know there are other options out there, open source and what not, but I never felt the need to try anything else out.

Something like this wiki page? There are some good charts showing trends at this site. That site also gives more context if you’re interested in digging.
