Earlier I really wanted to use whatsapp on my desktop. I tried many apps like bluestacks, nox etc. to use whatsapp on my computer but I can use it. Because there were lots of problems.
But when whatsapp released this concept, I was really happy and blessed I think. Now I can use whatsapp on my desktop with very ease. The usage is exactly similar as that of mobile phone. But the only problem is your phone and computer need to be simultaneously connected to the net.
Else everything so far is very good. You can do exactly what you do on your phone.
But it does not support calling features, I hope that whatsapp will update that so soon.
Thank you.
