I turned my father onto using notepad instead of word, as his laptop was old and slow and he kept complaining about the load time for MS word.
Two weeks later I hear this shout through the house:
"I can't get my notepad off my harddrive!"
I went in and discovered that he'd been saving to a floppy disk, but wanted a copy on paper to carry with him, so he put a pocket-sized paper notebook into the CD tray and tried to burn to it.
Oddly enough, that wasn't even his confusion. He said that worked fine (HOW?!?!?). No, the issue was that he'd taken the floppy disk out and was getting the message when he opened notepad that there was no disk in drive A:
I was speechless and had to leave the room.
