At Mobile World Congress today, HP unveiled the HP Elite x3 mobile device, which bridges phablet, laptop and desktop use cases. The Elite x3 is the first built-for-business device to deliver phablet, laptop and desktop business productivity in a single device. By utilizing Continuum in Windows 10, the Elite x3 enables multi-screen transitions between a phone scenario and a desktop PC scenario.

The phone equipped with Qualcomm's Snapdragon 820 SoC, which offers all the processing power to turn it into a PC.

To turn the phone into a desktop PC, HP is creating the "Desk Dock" that supports an external monitor. Plug the phablet into this docking station and hook it up to a larger screen. For a laptop experience, HP has a 12.5-inch diagonal high-definition display (Mobile Extender) that folds up with a keyboard and trackpad. The phablet will connect to the Mobile Extender through WiFi direct or a USB cable.

The Mobile Extender shows two USB-C ports on its right side, for data and power. A third USB-C port is intended primarily to charge the Elite x3.

The Mobile Extender has a 12.5-inch display and a backlit keyboard. Its three USB-C ports include one for charging the Elite x3, and two more for data and power. There’s also a micro HDMI port. Its 4-cell, 46.5wH battery can last three days in standby mode, per HP’s claims.

For apps that can’t run on the phone (x86), HP is offering a catalog of these apps that can be virtualized.
