There are literally dozens of keyboard accessories out there for tablets and even smartphones, but most of them fall into two categories. Either they present a comfortable full-sized keyboard but are uncomfortably bulky, or they are incredibly petite but inevitably result in tangled or cramped fingers. Since our mobile devices these days are just as useful for work as they are for play, LG has tried to design the Rolly Keyboard that fits both types. Its solution? Have the keyboard roll into a rather fat stick.
