>>1227245it certaily isn't low price but the gpd win2 is probably something noteworthy. it's an handheld gaming pc. it can be used for pc-games as well as emulation. of course you can run ordinary pc software as well. you can put it in your pocket and can be charged via (5V) USB/solar etc.
it's not rugged, though. the win2 however also can run linux, I heard.
