OK - here's one for the wide-eyed little seven-year-olds inside all of us.

What barbie doll do you wish they'd invented?

ME: Librarian barbie. Has normal feet that fit into comfortable looking shoes, naff cardigan and tortoiseshell glasses, and comes with a voice-activated "book trolley" that wheels towards you when you speak to it.

(Take that, Mattel).

You?
