Even as a tablet device, the Performance version is like seriously big that it may be difficult to hold and use at the same time. Perhaps you’re better off putting that down on the table and using it this way. I might have seen the device from Lenovo that is similar to this but for a big tablet device, it may look like it is useful for graphic artists for instance.
So, the specs are revealed for Panasonic Windows 8.1 4K Tablets and the Performance version is even more superior but more expensive. While the Standard version will be out in a few weeks, the Performance version will be out later this Spring.
