I don't own an iPad, nor an iPhone, so I'm not as interested nor up-to-date with the Apple iOS 6 news. But I am an observer of technology trends and it's been impossible to surf the web without hearing about the Apple iOS 6 Maps controversy.
Apparently, Apple has replaced the Google Maps with their own, and the results have been unfortunate. Here's a nice collection of the mistakes found. In a nutshell, Google Maps is better and those who upgraded to iOS 6 want their Google Maps back.
Here's my personal favourite image from Apple iOS 6 Maps. These are the rolling hills of Toronto Pearson International Airport.
