Soon enough you'll no longer have to worry about plug-ins to get to use Skype on Microsoft's new Edge browser. The latest build for Windows 10 Insider Preview has Object RTC API, which lets apps with real-time audio and video communication to work without any installation necessary. It'll work for things like Skype, Outlook.com, and any other WebRTC-compatible services. It's still in preview though so the experience might not be as seamless. It's said though that the tech should exit its preview phase and go live later this year. Other browsers like Chrome, Firefox, and Safari also support WebRTC standards, but we don't know if Microsoft plans to offer the experience there or make it exclusive to their browser.
