With Surface Duo, Microsoft has re-entered the phone business (sort of), with a dual-screen device running Android. The unique hardware and software combination makes it more than just a curiosity, even if it's likely to be a niche player at best.

Why it matters: Microsoft isn't going to suddenly become a major player in mobile hardware, but the Duo does give the company a novel option for Microsoft loyalists.

Details: Teased a year ago and formally introduced last month, Surface Duo becomes officially available today, starting at $1,400. AT&T will sell the device directly, while an unlocked version that works on all three major carriers will be sold by Microsoft, Best Buy and other retailers.

What's hot:

  • The design is elegant, useful and seemingly hearty: Of all the new crop of folding devices I've used, Microsoft's is the first that doesn't feel delicate and precious but rather built to be used.
  • Two screens makes for great multitasking. I enjoyed more easily moving among my mainstay apps: Slack, Outlook, Twitter and the browser.
  • It's first-class Android. By partnering with Google, you really do get the best of Android in terms of Google's apps and access to the Google Play store combined with all of Microsoft's mobile apps.

What's not:

  • The camera is the Duo's glaring hardware weakness. There's only one small sensor, and you have to fold your phone one way to take selfies and another to capture what's in front of you. That makes Surface Duo ill-suited for candid shots and results in an overall subpar camera experience.
  • Few programs are optimized for Duo's two displays, so you're usually just running one program in each screen. Over time, it would be nice if more programs make full use of the dual screens, as Microsoft has for some of its own programs, like Outlook, and Amazon has with its Kindle app.
  • The phone supports all the major LTE networks, but lacks 5G support. That's not a huge issue today, but could prove frustrating over the life of the device.
  • Surface Duo suffers from the same price problem as other multi-screen devices: It costs as much as two phones put together.

Cloud gaming services use iPhone's web browser door

One of the biggest trends in gaming is the ability to play console games wherever you are, on whatever type of device, thanks to the magic of cloud streaming. The tricky part has been finding a way to bring such gaming to iOS — since Apple wants to review and approve each game as a separate app.

Yes, but: Google, Nvidia and Microsoft have decided to work around, rather than with, Apple's rules. In recent weeks, all three have announced plans to bring their game services to iOS via the web browser — the one big opening in the wall around Apple's garden.

The acting administrator of the United States Agency for International Development informed senior staff Wednesday he has tested positive for coronavirus, two sources familiar with the call tell Axios.

Why it matters: John Barsa, who staffers say rarely wears a mask in their office, is the latest in a series of senior administration officials to contract the virus. His positive diagnosis comes amid broader turmoil at the agency following the election.

COVID-19 shows a bright future for vaccines

Promising results from COVID-19 vaccine trials offer hope not just that the pandemic could be ended sooner than expected, but that medicine itself may have a powerful new weapon.

Why it matters: Vaccines are, in the words of one expert, "the single most life-saving innovation ever," but progress had slowed in recent years. New gene-based technology that sped the arrival of the COVID vaccine will boost the overall field, and could even extend to mass killers like cancer.
