The Mirabook is a shell of a laptop that can be powered by your Galaxy S8, Windows 10 Mobile, or Huawei Mate 10
To use your phone in desktop mode, you need the appropriate dock — the Microsoft Display Dock for the Lumias, the Samsung DeX station for the Galaxy S8 or Note 8, or a simple USB-C to HDMI adaptor for the Mate 10. But you do also need a monitor, keyboard, and mouse, which can be a pain to lug around, right?
Well, company Miraxess came up with the cool idea to make a laptop that is dedicated to being a dock for your phone, nothing more. The Mirabook is pretty much a shell that offers a battery, keyboard, mousepad, 13.3" 1920 x 1080 screen, two USB Type-C ports and two USB 3.0 ones, an HDMI port, an audio jack, and an SD card reader. It houses an extendable dock, which you need to plug your phone into. The company calls this concept a "lapdock".
The Mirabook costs $249 and is compatible with the Lumia 950 and 950 XL, Acer Liquid Jade, HP Elite X3, Alcatel Idol pro 4, Samsung Galaxy S8, S8+, and Note 8, as well as the Huawei Mate 10. It's currently only available for pre-order and will, unfortunately, be ready to ship way in May of 2018, so... yeah.
