 It's Thursday, September 20th, 2012. I'm William Savona, reminding you to always wear your bow tie. This is 90 Seconds on the Verge. As more iPhone and iPad users update to iOS 6 this week, the frustration at Apple's new Maps app has intensified. People have taken to Twitter and Tumblr to post some of the most egregious failures. Apple replaced Google Maps service entirely with its own in-house solution. Unfortunately, it isn't quite the same level of quality and comprehensiveness. Google is yet to comment when or if it will release a native Google Maps app for iOS. Google is quick to remind you, however, that its Android app was just updated. Walmart is kicking Kindle to the curb. According to an internal memo obtained by Reuters, the retail giant will no longer sell Amazon's e-readers and tablets. The move follows a similar decision by Target, who cited a, quote, conflict of interest. That's not too surprising, given the Kindle lineup pretty much exists solely to sell Amazon content like e-books and movies, content you can instead get at, say, Walmart and Target. Walmart will continue to sell Apple's iPad, Google's Nexus 7, and even Barnes & Noble's Note. Yeah, it's getting personal. Finally, a logical connection between Hobbits and Half-Life. Peter Jackson's Weedle workshop has gifted developer Valve with a full-scale articulating portal turret, complete with a motion sensor and the turret's disturbingly friendly yet haunting dialog. Bullet's not included, thankfully. That's it for today's top stories. Tune in tomorrow to find out which humanoid behind me is actually a Cylon.
