The video shows the 6-incher Elite X3 being connected to the Continuum desktop dock that helps convert the smartphone into a desktop PC. The dock is connected to a keyboard, mouse and a big monitor. The Elite X3 is powered by a powerful Snapdragon 820 chipset with 4GB of RAM and 64GB of internal storage.
As for now, HP has not yet announced any prices for the phone or the Continuum dock and the Mobile Extender laptop. The possibility of the phone and the accessories launching would be later this year when Microsoft celebrates their Windows 10 Anniversary update.
