Do you live in an area with great public transportation? My phone is a necessity driving anywhere unless I want to take twice as long due to random spots of traffic.
The transit provider also recently introduced mobile fares, so sometimes I use my phone to board (QR-based.)
Unfortunately, there is another fare overhaul coming, whereby they will make fares account-based prepaid, and mobile fares will be mutually exclusive with the linked NFC card option. So unfortunately I will need to ditch the mobile fares entirely, because I do not wish to be constantly tethered to my mandatory smartphone if I simply wish to ride a bus somewhere.

The trick is knowing where you want to go - Google's search capacity to "find me a highly-rated Mexican restaurant with on the way from Work to Home", not turn-by-turn, routing, or even traffic, is the killer feature. Standalone GPS units have passable search, not just addresses, but nothing compared to that.
