Apple in a surprise move tonight reversed its no-cash policy for iPad sales. Responding to a TV news story of Diane Campbell being unable to pay for the tablet after saving up cash, the California company said it would allow cash at any of its stores as long as customers agreed to setup their Apple IDs at the store. Senior VP for retail Ron Johnson said he called Campbell personally and promised to have Apple deliver an iPad for free, with a case, in exchange for her trouble.
