Unsurprisingly, the Canadian company wouldn’t give a release date for either platform. Nevertheless, it’s clear that BlackBerry doesn’t want to just expand to mobile platforms Android and iOS; it also wants BBM on your desktop in one form or another.
It’s hard to make out, but BBM for Windows looks like an instant messaging client with the BlackBerry 10 design. Both publications present at the conference noted, however, that this is not a true desktop messaging client: it will require the smartphone app to function.
BBM for Desktop will thus work similarly to how BBM works on the BlackBerry PlayBook via BlackBerry Bridge. You’ll have to link your smartphone with your computer over Wi-Fi so that messages (as well as files and photos) are routed through your mobile device. In other words, you’ll still only be able to login to BBM on just one device.
A desktop option could give BlackBerry an edge in the cross-platform messaging space, as competition from the likes of WhatsApp and WeChat, which are mobile-only, is already quite fierce. There’s also Facebook Messenger, which is available on the Web (of course) as well as Windows.
