Everybody loves Whatsapp. More than 700 million people all over the world use it to chat with each other at anytime and from anywhere. It took the idea of old world chat messengers to the next level by combining it with your mobile numbers.
But just like many other phone only apps, people wanted to have an option to use it on desktop too. This is because many people still use their PCs as their primary modes of working and so it is distracting to work on a PC or laptop and then chat on your phone simultaneously. So, it is hardly a surprise that Whatsapp has done the inevitable by introducing desktop capabilities to expand its user base.
