Ok, so we were talking in the pub last night about putting a lighter into the sonic screwdriver.

So what ya gonna put in yours?
Lets make it a swiss army screwdriver.

Hologram projector.

good call.

and here was me thinking of boring stuff like lighters and usb stick thingies.

"Men in Black"-esque memory wiper.

...and maybe a spork that flips out of the side.

Also Wi-Fi.

@-j. - wanted one of them men in black dealies for ages.

@zephron: you already got one. I took it. *ZAP*

I'd just shy away from integrating weapons because the Doctor doesn't dig them unless they're 100% necessary.

i did ponder making it a lightsaber, seing as the new screwdriver is almost the same size, but then you wouldnt need to open doors if you could just slice through em.
