There’s something in the air this week. Maybe it’s that the holidays are coming, or that it’s getting colder, or that there’s not much actual news to be had three weeks before the Consumer Electronics Show. But for some reason, the dumb Apple rumors are piling up like so many discarded MobileMe accounts. The latest offender? You’ve probably seen it already: Retina iPad mini. Here’s why it’s a total waste of everybody’s time. Just to be clear, this isn’t the kind of rumor that’s dumb because it’s wrong. In fact, it’s the opposite: a rumor that’s based on something so inevitable, it has no merit as a rumor. It’s simply a statement of fact, one that’s been known since the day the first iPad mini came out. You might as well say that the next iPad mini will have a faster processor or a bigger battery or will run iOS 7. No. Kidding.
