I'm not sure how practical it would be if it ever existed, but a Korean company has created this rather interesting scroll-inspired MID concept design that I think is worth a quick look.
It's difficult to get an idea of the size of the "foldable glass monitor" that presumably coils up inside the ornate casing, but it features a large touchscreen area (no OS, I see) sandwiched between informational toolbars that display the language/time and mode options.
I actually kind of like the whole scroll thing, as the idea of pulling out a fully functional screen from what simply looks like a decorated tube appeals to me for some reason, but I wonder how sturdy the display would be when extended. It would obviously have to be able to withstand a certain amount of pressure without flexing like a piece of paper or flying back into the housing while you're interacting with the screen.
How would you interact with the screen anyway? My first thought would be that you'd have to lay it out on a flat surface; it doesn't seem like a one- or two-handed device to use while lounging on the couch or walking around.
I doubt that something like this would ever really be released anyway, but I still wouldn't mind giving one a try.[tech.163.com (trans)]
