The Amazing iOS 6 Maps
The "roller coaster" effects in the 3-d view are my favorite. They've got some smoothing algorithm going, or it wouldn't curve the way it does, but the elevation data must not have a high enough resolution.  Google has made this sort of thing look so easy for so long, but it's clearly very hard to get this stuff right.<p>So, I guess it's not that surprising that apple messed up something incredibly hard in their first attempt.  I'm curious as to whether these issues are as widespread as they seem, or if they're more edge cases made to appear common by  the internet.  But the curiosity isn't enough to drive me to upgrade.  I'm totally putting off that until I figure out a decent alternative app.
