WhatsApp Web is the newest cool stuff from the WhatsApp team which is a web browser based WhatsApp client. It lets you to access your WhatsApp account without the official WhatsApp installed or without a smartphone or a Tablet computer. So everything is great. But.. the strange thing is you cannot access WhatsApp Web without a smartphone with App installed (need to scan QR code through App), and also need to keep the phone online to keep web client live. So my question is why we really need this Web Client ??
