@Fubarberry for on the go i have a foldable bt keyboard with trackpad and, if i feel fancy, a little projector that can be powered by a powerbank. For at home i have a 13" screen with an arm that i can clamp onto the nightstand or on the workbench and a cheap wireless logitech m+k combo. If i ever feel the need to game docked instead of handheld i'd probably use my xbox controller or maybe the steam controller
