Despite the name, LG's Rolly keyboard doesn't really roll. Instead, the Bluetooth peripheral unfolds segment by segment, with four rows of keys laying neatly on any flat surface or clacking magnetically into place around a square spine. As a rod, the Rolly feels neat and balanced, and although it is too long to stow in your pocket, you could easily slip it into a bag and forget about it.
However, there are a few irritants in using the device. When typing, your fingers are either bumping into the top or tapping fruitlessly on magnetic blank keys that run down either side of the device. That being said, the keys themselves are satisfying to use and the Rolly boasts a Bluetooth pairing functionality which lets you connect it to two different devices at once.
The battery bar also holds a pair of concealed arms that let you prop up a tablet or smartphone at a laptop-like angle for doing work, and LG claims that the Rolly will run for three months on a single AAA battery. It is expected to retail for around $119 in the US sometime this September before heading to select countries in Europe and Asia before the end of the year. If you are in the market for a portable keyboard it is worth considering the rolling option.
