Those aren't nearly as cool looking although I'd still want one. Unfortunately, these kinds of devices are more expensive than they should be considering that they're marketed as toys/experimental devices. Once you go over $100, it's more cost effective to just pick up a cheap second-hand laptop instead, though they're not pocketable and certainly a lot more boring.
Also, it bugs me that the ClockworkPi seems to be RISC-V powered - they should change the name for those and fully get on the RISC-V bandwagon.
My zipitz2 costs far less and it was an amazing tiny serial console (with an 80x25 cli with a tiny font) and a sdl2 based GUI. I could emulate the NES, play nethack/slashem, IF, mp3, join MUDs, connect to wifi to browse webs with lynx and links, read epubs with a custom script with unzip and elinks...
