The Apple iTablet is just about the hottest device that may not actually exist. While most of the tech world seems convinced that a 10" touchscreen tablet is on the way from Cupertino, we still have no hard proof of it. That's why bloggers are scrambling desperately to find any and all information that makes the iTablet seem more plausible, or gives us a better idea of its (possible) capabilities.

AppleInsider reports that some folks have taken Snow Leopard's revamped on-screen keyboard as proof positive that the new OS will play a big role in the iTablet. This new soft keyboard is larger than the one in Leopard, and it is easier to access as well. Snow Leopard's keyboard can also expand to fit the entire width of the screen. To some bloggers, that equals a smoking gun.

Any sort of tablet product would rely heavily on an on-screen keyboard. Thus, the fact that Snow Leopard features a dramatic improvement in Leopard's soft keyboard could be a sign that Snow Leopard is meant to run a tablet, too. I can see the argument they're trying to make, but I'm still not entirely convinced.

When you go out in search of proof, you usually find it. That doesn't mean whatever you're trying to prove actually exists, however. We've seen a lot of "proof" that the iTablet is in development, but not nearly as much hard evidence that such a product is actually coming. Take this, and all iTablet rumors with a very big grain of salt.
