One of the more interesting accessories that Samsung introduced alongside its Galaxy S8 is something called the Dex — a small docking station that turns the new smartphone into a computer by connecting it to a monitor and keyboard. When plugged into display, Dex is capable of running multiple apps, including mobile versions of Office in resizable windows. But while it can render desktop pages in its browser, it can't do Flash.
Why it matters: While it makes theoretical sense to have a single device that can be a smartphone and then turn into a full-fledged computer as needed. In practice, such efforts have rarely been enough of a computer for those that really need one. If anyone ever gets it right, they could grab a nice chunk of the phone and computer market.
