 It's Monday, July 16th, 2012. I'm David Pierce, and this is going to be the best 90 seconds on The Verge today. Former Google executive Marissa Meyer is now CEO of Yahoo. Meyer led the teams that developed Gmail, Google News, and all the company's location services. She replaces Scott Thompson, who was ousted after only five months when it was discovered he falsified his resume. Meyer comes in with a very real degree in computer science from Stanford. She begins work tomorrow. Microsoft has released the consumer preview for the upcoming Office 2013. We've spent some time with it, and aside from cloud sinking and a more Metro feel, this isn't a crazy departure from the last version of Microsoft Office, or any version, really. Office 2013 is compatible with Windows 7 and 8, but not Vista or XP. But then again, if you haven't upgraded Windows, why on earth would you be interested in upgrading Office? This weekend at Comic-Con, Microsoft unveiled a limited edition, Halo-branded Xbox 360. For $400, you'll get a specially branded console with matching controllers, plus a copy of Halo 4. The bundle will be available November 6, the same day as the game's launch. Sprint has officially launched its 4G LTE network in 15 US cities, including Atlanta, Dallas, and Kansas City. The carrier says it will announce more cities in the second half of this year. Skype confirmed today a rare and unfortunate bug that would occasionally cause messages to be sent to the wrong contacts. The company said a fix is coming in the next few days. For now, please defer all your gossiping and trash talking to Gchat and AOL Instant Messenger. And that's it for today's top stories. Tune in tomorrow, where I will be going kidneys on with the very latest in synthetic organs.
