The old LG Rolly Keyboard had only four rows of keys. We can't even believe we lived through such primitive times. Because of math, the old keyboard rolled up into a square, but the new keyboard rolls up into a pentagon. Finally we can live all our cyberpunk fantasies of having five rows of keys in our rollup Bluetooth keyboards. Thank you, LG Rolly Keyboard 2. You cost 129,000 KRW, because you are only available in South Korea right now, but that's roughly $112 USD. You have five rows.
