During 2010-2017, I worked on creating a "pocket server", the size of a keyfob, which would be the basis of a pads/tabs/boards personal computing environment. It would connect to any number of local screen devices via Bluetooth or Wifi Direct. It failed because I had no prior experience of developing hardware, and had rather a lot of back luck with HW engineering contractors and contract manufacturers.
