Portable computers have looked like hinged books for long enough. The D-Roll concept looks back even further than the codex to the humble scroll for its inspiration. Plus, you can carry it like a purse!
D-Roll, which stands for "digital roll," is a concept from designer Hao Hua. It features one long cylindrical base from which the screen unfurls in one direction and the keyboard in another. When rolled, you can use the attached straps to carry around the D-Roll in classic purse or man-purse fashion. Sure, our future laptops aren't necessarily going to look like this, but to quote Dennis Duffy from 30 Rock, "Technology is cyclical!" [DVICE]
