LG Rolly is a portable keyboard that turns into a stick

The portable keyboard is a problematic gadget — to make sense, it needs to be big enough for a human to type on, but it should also be as small as possible.
LG has tackled the problem with its Rolly Keyboard — an almost-full-sized keyboard that collapses into a stick. Yes, the stick still has the keyboard's length (LG did not disclose the keyboard's size), so it's not exactly pocketable (though LG claims it is). In any case, it's definitely more portable than a non-foldable keyboard of that size.

The keyboard has four rows of keys — two less than your regular keyboard, with numbers and function keys rows missing. The numbers, however, can be accessed on the top row using the function key on the bottom.
Rolly is made of "impact-resistant and durable polycarbonate" and ABS plastic, and has two foldable arms that keep a smartphone or a tablet (up to 10 inches in size) in an upright position. It's wireless and powered by an AAA battery which should last up to three months of average use, according to LG.

LG's Rolly Keyboard will hit the U.S. market in September, and will become available internationally in the fourth quarter of 2015, at a yet-undisclosed price. Let's just hope it fares better than Sony's Rolly music player.
