We've come across various tablet concepts in the past, although we have to admit that the Four concept tablet by Marko Vuckovic may very well have taken the cake in terms of design. As pictured above, Four is a concept tablet that measures 145 x 235mm and based on its features and renderings, it appears to be a tablet designed for the home in mind, allowing it to be hung up on walls to double as digital painting while providing its user with a variety of functions and features.
Ubergizmo, The Four tablet concept is breathtaking
