the understatement: Quantifying the Impending iOS 6 Maps Backlash:
On the plus side, at least people are getting turn-by-turn directions and Apple’s Flyover feature in exchange, right? Not so fast: 20 countries (population: 3.2 billion) are losing transit, traffic, or street view and getting neither turn-by-turn nor Flyover. The biggest losers are Brazil, India, Taiwan, and Thailand (population: 1.5 billion) which overnight will go from being countries with every maps feature (transit, traffic, and street view) to countries with none of those features, nor any of the new features either.
It gets worse. Even in countries where turn-by-turn and/or Flyover are available, the iPhone 3GS, iPhone 4, and the 4th generation iPod touch won’t support them. These devices are owned by tens of millions of users who may update over-the-air when prompted, only to find they’ve lost features and haven’t even gained any of the marquee Maps features in return.
Based on past data2, it’s likely that at least 200 million users will upgrade to iOS 6 in the next two weeks. Even if only 1 in 10 people are upset by these changes, Apple will have 20 million unhappy customers on their hands, roughly equivalent to the entire population of Australia.
