20-inch Windows 8 tablet by Panasonic boast 4k resolution

If bigger is better, the Panasonic might just be the best at CES this week. The portable tablet may just be the largest of its kind and the insane resolution - 4k - is unmatched. At less than half an inch thick, this device would target professionals on the go with it's pen interface and visually-stunning display.

We don't know a lot about it yet, but expect it to be pricy. According to TheVerge:

With such a pixel-dense display, you'd get incredibly detailed control using a stylus, and most of the company's on-stage demos showed how much you can do with so many pixels.
