I hacked together a prototype of the previously-mentioned handheld portable computer, using a Raspberry Pi 4 and 5 inch LCD touchscreen. So far it is really nice to use! I like how I can use a full desktop OS while walking around. The keyboard and trackpad allow me to use a regular OS without having to worry about touch affordances, mouse-overs, and right-clicking. There is scope to make this much more compact if using a 3d-printed enclosure. #diy #raspberrypi #handheld #portable #computer
