The pixels on Panasonic's new 20-inch 4K tablet are so itty bitty that I couldn't even see them when I pressed my eye almost to the tablet's touch screen. The viewing angles for the tablet were excellent. But they're going to have to up the power of this baby's guts if you really want to take advantage of its potential.

The 15:10 tablet in Panny's booth at CES is relatively stacked: Windows 8 Pro on an 1.8GHz Intel Core i5 processor with NVIDIA GeForce Graphics, 4GB of memory and an 128GB SSD. Even with those powerful specs, the high-detail applications Panasonic envisions for these tablets don't move as fast as you'd expect.

Swiping and dragging can be very slow on large documents, but the insane detail of the screen and the precision of the touch-sensitivity are impressive. Using a Panasonic stylus, you can draw very finely and make very precise edits in Photoshop.

But as those applications indicate, this tablet is really intended for business and professional use if (when?) it ever sees a commercial release. Most people probably don't need resolution that high on such a small screen. Still, with some beefed up speed, this thing would be a beast. And as a proof of concept, it's pretty amazing how many pixels we can pack into such a small space.
