The future might be mobile, but for now plenty of us still use a computer. WhatsApp has finally conceded that point, releasing its very first desktop app. You've been able to use WhatsApp in a browser window for a while now, but the new app -- available for Windows (8+) and OS X (10.9+) -- just sits on your computer like any other piece of independent software. To set it up, you just scan a QR code using the app on your phone, then it mirrors your messaging history across both devices. And, honestly, there's not much more to say other than: Maybe go download it.
