I use an iPhone, keep all my casual media and textbooks on an iPad, and use a MacBook Pro for work. I'd really like to use Apple if I could, but I have no idea why all these people are supporting Apple maps.
I tried desperately to use it for half a year (in the US), gritting my teeth at the endless frustrations. From the inability to get info on any business or location other than a highly biased Yelp popup, to the voice directions telling me to turn as I'm approaching the turn before it actually wants me to turn, to the flat-out wrong streets. I've found myself being led to random dead-ends that the map said should be a thoroughfare, but obviously never had been and would unlikely be in any near future.
Similarly, I'm astonished at the bad service in their cloud, files, photos, music, and suite of office document programs. Just terrible for such a huge company. I can only conclude that they don't care, since they're making more than enough money on hardware.
