but it comes pretty close (approximately 1000m close, on average)
1000m by average kinda sucks....
guess its one of theose things youll have to try and see for yourself !
Its sucky as a GPS but theres a lot of possiblities from knowing approximately where you are.
Beside automatically starting google maps in the right area, narby restaurants, etc (which is what its really for) the same info could start relevant weather reports and nearby traffic info (1-2 kms is good enough for traffic jams and clouds). Theres a ton of other uses.
Say I always want my mobile on vibrate when Im at work but ringer on at home. You could use the same info on location to auto switch between the two modes. It could know which direction youre travelling in and automatically warn you about train delays at your destination only (who needs the info along the whole route - just where youre going). Working out which airport youre in to only show you the relevant flights. Automatically warning you about events like local football grounds kicking out, etc.
Its got a lot of potential for just making general everyday apps run that little bit smoother. They shouldnt have called it GPS as everyone thinks of using it for navigating. But I do like the idea if other people start to use it.
