Cam gives an overview of the BlackBerry Blend software. Since the company doesn't make PC's, or computer OS, it can't bake continuity in to the software and so it's created a compelling desktop program. It essentially offers a mirror image of everything on your BB10 device. You can read and send SMS, emails and BBM messages. You can read and edit your calendar, organize your Hub, view BBM channels and open the file manager to import images, videos and documents.
What's perhaps more impressive is that you don't need a USB cable or Bluetooth connection to do it. You can connect via local Wi-Fi, or even using your BlackBerry ID through the mobile cellular network.
If you've set up your BlackBerry in a specific way, the way you want it, there's no better way to manage all your communications away from your device, than using Blend. It's fantastic.
