Hot location fixes are much faster than warm fixes, even with aGPS. Turning GPS off usually causes a substantial delay before you can start using a location-dependent app or feature, plus the manual effort of turning GPS back on. The delay is far greater if you're in an urban canyon with high levels of multipath interference. For a suburban user that occasionally uses driving directions, this delay probably isn't an issue. For an urban user who is frequently using maps, location-based searches, ridesharing apps etc, it's a total dealbreaker. If I'm the kind of person who often says "OK Google, where's the nearest coffee shop?", I don't want to have to turn on GPS and wait for a location fix before I get a useful answer.
