Weekly Tech Highlights: BlackBerry Might Use Android, Twitter's CEO Shakeup And More

This week was filled with smartphone surprises, CEO shakeups and the future of streaming music.

could be on the verge of a massive, unexpected change. The company, once famous for making email portable, is rumored to be developing a handset that will use Android. "BlackBerry should have done this two or three years ago," Sean Udall, CIO of Quantum Trading Strategies and author of The TechStrat Report,

. "If they didn't have to spend a bunch of money developing OS software, focused on their own network and security and gave up on the hardware side of the business, what do you have? A software company with pretty high margins." Global Equities Research analyst Trip Chowdhry didn't share the same positive outlook. "That tells me the fundamentals are deteriorating because there's nothing else left for them to do than to be a complete me-too [company]," Chowdhry told Benzinga. "Then they [can] focus on device management and other stuff, which is good. But it seems like they are having some problems executing on that front also."

surprised investors when CEO Dick Costolo resigned this week. "Something had to break the stock because the algos and market makers and hedge funds were getting way too confident," Udall, an expert on all things Twitter,

. "I told a friend the other day that there was no way I will sell any Twitter right now because any day the stock could pop three to four points on basically nothing. [But] I didn't think this would happen."

It all started with iTunes. Now

is getting ready to launch a subscription-only, on-demand music service. "I think it's a me-too service," Chowdhry

. "I think there are better platforms that have better discovery and [provide] a better experience and [a] better music community." Chowdhry reiterated his disappointment with the Beats acquisition, which led to the creation of Apple Music. "I think Apple's acquisition of Beats was a completely useless acquisition," he said. "The headphones aren't going anywhere. I think Apple Music, what you're seeing, is a pretty useless announcement. I would also say Beats' acquisition was very shortsighted."

According to

, WatchESPN and Sling TV typically account for less than one percent of traffic. That changed during Game 1 of the NBA Finals. "What we're seeing -- more and more -- [is that] when there's a live event, people stream it," Mark Fisher, VP of marketing and business development at Qwilt,

. "That used to be the worst possible option because the experience was so bad. And now what we're seeing is [that] it's pretty good/getting better because people need that kind of flexibility. They have a mobile device, who knows where they are, and they want to stream. We see that as a good thing."

Founded by former

exec Claus Moldt,

offers a drag-and-drop user interface for quick and easy app creation. "One of the other very attractive features about what we're building is our target customers will be small, medium and large enterprise-scale businesses," Randall Kaplan, chairman of m>PATH,

. "Each of which has their own specific needs and each category will be able to address, whether your company has five employees or 500,000 employees." Disclosure:
