Microsoft has been talking about Windows Continuum—the ability to power a laptop or desktop-style PC experience from a Windows smartphone—for some time now. HP's Elite x3 is a Windows 10 phablet that's designed to deliver a fully realized version of that experience.
The Elite x3 can link wirelessly with an optional "Mobile Extender," basically a 12.5" laptop without any PC guts. For desktop mode, the phone can be placed in an optional dock that includes a single DisplayPort, two USB-A ports and one USB-C port, and wired Ethernet. The video below shows how all of this works.
That experience is powered by the popular Snapdragon 820 SoC. Interestingly, HP elected to go with an ARM SoC rather than an x86 chip in this device. HP will provide a method of virtualizing x86 apps on the Elite x3 for users who need it, though.

The Snapdragon 820 is paired with 4GB of and 64GB of storage that can be expanded by up to 2TB using microSD cards. The phone sports a 6" 2560×1440 screen. HP also seems to be appealing to business users by including iris and fingerprint scanners, wireless charging, and a huge 4,150mAh battery on the device, as well. The phone also includes a 16MP camera on the back and an 8MP selfie-shooter up front.
So is the Elite x3 really the one ring—err, device—to rule them all? We'll have to wait until this summer to find out, but the concept certainly looks promising, especially for light office work and productivity on the go.
