"With the addition of desktop apps, WhatsApp is now available pretty much everywhere: On all major smartphone operating systems (Android, iOS and Windows Phone), through web browsers and now on the most popular desktop operating systems. The desktop software will allow users to message friends sending images, video and audio files, but initially at least, it won't allow for voice calls to be made.

The only other app with such ubiquity is Skype and with video-calling still not available on WhatsApp, it retains a key appeal for users. However, code within a beta version of its iOS app indicated that video calling is being developed and if this is rolled out to all platforms, it could have a significant impact on Skype's business."
