one device multiple screens by hidetaka karube from japan

As computers evolve throughout the years, they've become smaller, lighter, and faster. Hard-drives have become smaller, computing has become faster, and as with tablets, they've basically become one with the display.
In the year 2020 though, the hard-drive, computing, and display will all be separated from each other. The hard-drive will be online storage, or the cloud. The computing will be done on a mobile phone that everybody will have. The mobile phone will access the online storage via a private and secure network(unlike open and local wi-fi networks), and mirror the content to bigger displays found in cafe tables, LED Papers, television, or even on house windows.
Anybody can work out of the office on cafe tables or watch a streaming movie with your friends on a LED paper, with just a mobile phone.
