no, they're plastic crap for kickstarter photos. not designed for human hands.

They once existed (see Sony Vaio P 2nd gen; coolest thing in the universe) but modern OEMs no longer have such taste.

The ideal "cyberdeck" form factor is just a regular laptop. So to the extent that a macbook pro counts as a cyberdeck, yes.

More of a fun Maker project for sure

For general compute they will lose to a laptop, but that isn't supposed to be their purpose. I think the best use cases require extra hardware that would make a laptop too bulky or awkward. For example a deck with a VNA, SDR, scope, and arbitrary waveform generator for field work with radio equipment. The traditional computer capabilities are sort of extra. Any sort of diagnostic "cart" with a dedicated computer and a bunch of test equipment could be a candidate for miniaturization.

Been working on a handheld cyberdeck with a good thumb keyboard. I'm masochistic enough to write entire projects on my smartphone with vim running inside termux, so I think anything that improves on this will certainly be used.

Measured my thumb's swiping arc and designed a split keyboard specifically for my hands. Managed to get every symbol in there with no layers. Now I just need to save up some money and order protypes so I can get a feel for the switches. Can't move forward until I've perfected the keyboard.

I got a ClockworkPi uConsole and am not really using it much, and that’s because it’s become very hard for me to read on the high dpi small screen for too long.

I'd be very interested in reading about the kinds of hardware projects you're doing with esp32s and your printer!
