 It's Wednesday, March 20th, 2013. I'm David Pierce, worker of wonders, master of Prestidigitation. This is 90 Seconds on the Verge, brought to you by Mercedes-Benz. Google Keep is now official. After briefly showing up on Drive earlier this week, Google's note-taking and list-making app has launched for both the web and Android devices. Basically, it's designed to be like sticky notes. It's supposed to be a really easy way to capture stuff that you want. It's a bare-bones service for now, but we're hoping that Keep will someday integrate with Google's other services like Gmail, Calendar, and of course, Docs. The alternative, sadly, would be Google dropping Keep during one of its spring cleanings years from now. Too soon? Sorry. Samsung's 4K easel television now has a price. As you might expect, it ain't pretty. The 85-inch set, now dubbed the S9, will cost $39,999. Samsung says the S9's high contrast ratio and quote, ultimate dimming control are among its most important features. But let's be honest, it's really the easel. Pre-orders begin at the end of the month. Start saving. And finally, Twitter now has a patent. For Twitter. Originally filed in 2007, the patent broadly describes a service in which users follow each other and messages are broadcasted without specific recipients. In other words, Twitter. It's doubtful the company will pursue any litigation against competitors, however. Twitter has very publicly promised to only use patents defensively. Fun fact, founders Jack Dorsey and Biz Stone are listed as the inventors, which is way cooler than being verified. And that's it for today's top stories.
