I had a Palm Pilot in their early days just because it was on sale somewhere. I couldn't really find a tremendous use for it and it kept making beeping sounds that would irritate my professors who kept telling us to turn off our phones which mine was not on but I didn't know how to make the Palm Pilot stop doing that. I recall one lecture where I just put my bag out in the hallway after explaining to the teacher that I wasn't doing it on purpose. I'm surprised security didn't take it away as a bomb scare.
