Wishing upon their iPads
Fans dream up ways Apple can perfect its popular tablet
Will the next iPad talk? Could it get any smaller? What about a beefier camera or souped-up processor? Rumors about what might come on a third-generation tablet from Apple Inc. have swirled since it revealed last week a big announcement coming on Wednesday. “We have something you really have to see. And touch,’’ it said on invitations to an event in San Francisco. That sounds like it could very well be the iPad 3. Apple lovers hope so.
