We just told you about the stunningly-high-resolution 4K tablet Panasonic unveiled today at the CES. Now we get to spend a little time with the tablet ourselves, and see just what the fuss is all about.

The 20-inch prototype sports a massive 3840 × 2160 resolution and runs Windows 8 Pro. It’s got a viewing angle of over 170 degrees, and Panasonic envisions it being used by the likes of architects or designers. With a screen this big, though, you’ve got to expect that battery life will take a hit, and Panasonic says you could hope to get about two hours out of it. The tablet is less than half an inch thick, and weighs roughly five pounds.

While this is just the prototype we’re looking at, Panasonic intends to get it ready for commercial sales before the end of the year. Just what you’ll end up paying for this behemoth hasn’t yet been revealed.
