An analog computer that I'm not giving up is my dial caliper. Accuracy aside, the dial "updates" itself continuously, and you can even anticipate where it's going to settle. It takes a very high quality (expensive) digital caliper to match the responsiveness of the dial. I'm not giving up the nice analog stereoscopic microscope in my workshop. Digital microscopes exist (still the optics are analog) but actually making a user interface that's as snappy as human vision remains a hard problem, and companies like Keyence who succeed at it aren't making it cheap. These are user interface issues rather than accuracy issues. A problem with bringing many archaic technologies into the digital domain is actually understanding what problem they were solving. (I'm also not giving up my nice Mitutoyo vernier caliper, but that's more of an aesthetic thing).
