Cyberdecks are nice for photos and build blog posts, but does anyone actually regularly use them?
At CCCamp 2023 was someone showing off how they converted a laptop with a broken screen into a cyberdeck by removing the screen and permanently connecting the bottom half to VR glasses.
There was also a musical Tesla coil. And some group called Anderstorp, who converted a massive obsolete router into a beer tap.
I became an engineer because I'm lazy.
I recently got a (good!) 3D printer, and that combined with Claude has got me building lots of custom hardware devices using ESP32s.
I don't really see the value in a full-computer experience (which seems to be what most cyberdecks try to do - badly) but I can see utility in "sidecar"-style hardware, which is more akin to a phone app but with a better experience because of custom hardware.
