Panasonic introduced a 20 "tablet

At CES 2013, Panasonic introduced a 20-inch tablet with a screen resolution of 4K.We missed reporting on this, but in times when people are slowly starting to migrate from bigger 10-inch tablets to the more convenient 7-inch ones, Panasonic has decided to go the other way. It’s a giant of a tablet sizing up to 20-inches with a 4K resolution display screen.

The tablet certainly attracted a crowd of onlookers at Panasonic's CES booth, likely drawn by its monstrous screen. The tablet has been designed with a wide viewing angle so 4K content can easily be shared with others.

The screen displays images at a 3840 x 2560 resolution in a 15:10 aspect ratio, which leaves the pixels almost imperceptible from up close. It uses a 1.8 Ghz Intel Corei5 processor to smoothly run applications on Windows 8 Pro, including Adobe Photoshop. An accompanying digital pen can be used for precision and to record natural handwriting, but a finger works just as well for swiping through pages and general navigation.

It's quite a bit heavier than other tablets on the market at 5.3 lbs (2.4 kg), but that's to be expected with the much larger screen.
It has following specification Processor 1.8GHz Intel Core i5, graphics card NVIDIA GeForce Graphics, 4GB RAM, 128GB SSD. The only disadvantage of the gadget represented include battery life, which is only 2 hours.
