Panasonic is ready to go to the next level in PC and tablet resolution. Is anyone else?

Ultra HD/4K televisions blanket this year's Consumer Electronics Show like freshly fallen snow, but Panasonic is standing alone in demonstrating 4K technology in a personal computer. The company's 4K tablet prototype on display at its booth has a ridiculous 3840x2560-pixel resolution, with 230 pixels per inch packed into a 20-inch IPS LED-backlit LCD display.
The 15-inch Retina Display MacBook Pro has a 2880x1880-pixel resolution at 220 ppi. There isn't a 20-inch display currently in a computer that boasts that pixel density and resolution, but the demo unit was notably laggy when loading photos and pinching-to-zoom, or navigating around Windows 8.
The sleek, brushed-metal, 5-pound Panasonic tablet prototype runs off an Intel Core i5-3427U processor, Nvidia GeForce graphics (unspecified), 4GB of RAM and has a 128GB SSD.
