yes there are. Many languages have special characters and have special keyboards to accommodate them, eg, Germans have a different key set. Of course Japan, China, Russia have different key set. But even within one language there are keyboards that fix the strange key layout (Querty) that we are saddled with. there are keyboards that address the comfort problem with a split in the center and special places to rest your hands. And then there are different construction techniques with different types of key switches, some that are less prone to water damage.
