It’s quite possible that Microsoft has a product in development that could give Apple’s long-rumored tablet device some real competition. The potential product is apparently called “Courier,” and according to images and video leaked to gadget blog Gizmodo, it’s pretty freakin’ amazing. At first glance, Courier looks more like a booklet than a tablet. It opens and closes like a book, and it appears to be bound in a leather or faux leather cover. Each side sports a seven-inch-or-so screen, and when closed, it might be less than an inch thick.
