I feel the same gut reaction when I see projects like a cyber deck, or people building old pentium computers but I also do the same thing, I seem to keep rehashing things (variation of a note taking app). Only thing I can think of is the joy of doing it. Expanding further, it's easy nowadays to get a pi and attach some HDMI screen to it and battery source. Gets the job done, do I need to personally write a graphics driver for it to be impressive idk. In the long run I am trying to learn harder things though so my skills are not commoditized.
