 It's Monday, February 11th, 2013. I'm John Lagomarsino, and this is 90 seconds on the verge, brought to you by the letter B. Apple has begun development on an iOS-based smartwatch. That's according to both the New York Times and the Wall Street Journal this weekend. Sources tell the Times that it'll be made from curved glass, which would set it apart from competitors like Pebble. Rumors of a so-called iWatch have been circulating since at least 2011. Finally, a way to play Angry Birds on the go. Amazon's Prime Instant Video is inching closer to Hulu, thanks in no small part to CBS. Amazon Prime customers will have exclusive online streaming access to Under the Dome, an upcoming series based on Stephen King's 2009 novel. What makes this so special? Each episode will be available just four days after it airs on TV. Amazon typically doesn't add episodes until the season ends, and this new approach brings it closer to Hulu's day-after approach. Under the Dome will premiere on CBS in June, and on Amazon in June plus four days. Finally, after six months, the Curiosity rover has started drilling into Martian bedrock. According to the official Twitter account, the goal here is to collect samples, quote, for science. More specifically, Curiosity is searching for evidence of water in the Gale Crater to see if it's ever been capable of sustaining life. NASA engineers will analyze the samples over the next few days, which is suspected to drastically alter any future adaptations of Total Recall. And that's it for today's top stories. Tune in tomorrow for the letter C. It's for cookie.
