I sometimes answer the front door in pyjamas and/or dressing gown. This is not an emergency scenario (yet), but if I take the time to put on underwear and trousers the person at the door might have given up and left. So having EDC at bedside suits me.

Likewise if my mobile phone rings at 3am I don't want to have to get out of bed to find it. And anyway, I sometimes read a book on the phone last thing before sleeping. So the phone also lives on the bedside table at night.
