@rntz i am therefore gunshy about using anything too weird and custom and nonstandard because if it breaks I probably can’t just use someone else’s device. my approach is more “put as little technology on the critical path to a functioning presentation as possible”
@chrisamaphone I think I'm not quite as gunshy as you, but if I do have a related practice: if my talk involves a live demo & I'm not confident it's gremlin-free, I screen-record a video as backup.
