Android Pick: Skype Preview
Paul Thurrott's pick of the week on Windows Weekly 506 is the new Skype Preview for Android. This is a pre-release version of the new Skype client for mobile. It's a lot like Skype Preview as we see it on Windows 10 today. It has some features that are not available in the standard Skype client, plus it has a brand new, prettier user interface.
If you're on iOS, there is a closed beta. You can access it by applying, and you can get instructions for how to do that at thurrott.com.
