CES 2013: Panasonic has been demonstrating a prototype of a 20″ tablet at the CES show in Las Vegas. The large 3:2 tablet is built around a 4k, 3840×2560 pixel IPS display, giving a resolution of 230ppi. The tablet runs Windows 8, meaning it can run full PC software such as Adobe Photoshop. The prototype included a 128Gb SSD to allow fast access to images stored on the device. It also includes a standard USB port for connecting a card reader but only has a port for microSD cards built in.
