Right now I have 4 things, though it often swells to 6+ with chargers:
1. Clock radio
2: Lamp
3: Scanner Charger
4:Streamlight Stinger (Flashlight) Charger/cradle

If I'm dealing with a custom house, I'll at least put a 4-plex on each side of the bed, though I have, at the owner's request, put a 4 gang in on each side. If I was building my house, I'd do at least that, or maybe a quad and two single gangs to handle all the adapters things have these days.

Wiremold add on boxes can turn a duplex into a quad (or more)
