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.
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.
