"Anything you can do, I can do better." That seems to be, or has always been, Samsung's theme in its rivalry with Apple. It was the first to out a 12.2-inch tablet, larger than any Android tablet or iPad ever conceived. Now that Apple is rumored to also have a large iPad Pro coming soon, Samsung is raising the stakes by increasing the size. How big, you ask? Well, 18.4 inches, according secret sources. Big enough to be called a table rather than a tablet.
