Almost immediately after the launch of iOS 6 on Sept. 19, users who updated their existing iPhones began griping that Apple's new Maps app was substandard at best, a debacle at worst. They cited the lack of public transit maps, wild inaccuracies, off-kilter points-of-interest, Salvador Dali-like images, vacant countrysides, missing streets and addresses, and more.

Some analysts said there was for what Apple offered iOS 6 users, while others urged Apple to aggressively push Google to submit Google Maps as a stand-alone app on the iOS App Store.

The most frequently-tweeted problem with Apple Maps was the lack of public transportation information, something Google Maps offers, and a feature Google has spent years accumulating and tweaking.

Of all tweets that mentioned problems with Apple Maps, 56% were complaints about AWOL public transit data.

"So looks like the new Apple Maps on iOS 6 doesn't show public transit directions. That's my deciding factor, that's probably what I use most," tweeted one user.
