It would be really nice to get an OsmAnd port. Doubly so, since that would also make it available as a Gtk app on desktop Linux with minimal changes.

What about the location and GPS hardware and the security and privacy concerns that come with them? I'd rather just give up nav. Again, I'd still pay more than an iPhone without the location hardware. Could still do manual direction searching on the web, though I secretly want to go back to paper maps.

That's only a problem if you don't control the software.

When you're using web maps, you do not control the software - they request location, you give access to it (because you want your maps to show where you are), and you don't control that location information once it leaves your phone.

You don't need webmaps. OSM data are free to download and render locally. Navigation devices have offline maps, typically.

GPS is passive. Ideally they would just know which place you're requesting data about.
