I’d like to sell some puzzle books I’m creating, say at the local airport. But I can’t afford a regular cart. So how about a mini-one? Basically, it would be a portable store, wirelessly ready to accept credit cards, print receipts, store change (that’s in my pockets). Design it all up, and you’ve got yourself the me-osk, the portable kiosk. Pockets, hats, shoes, your belt — the whole outfit could help play a role.
