A split keyboard enables users to place two keyboard halves at a distance that's more conducive to natural hand positioning, reducing strain while typing, and facilitating a more comfortable overall work experience. Split keyboards are a popular ergonomic keyboard choice because they eliminate so many pain and discomfort issues with a very low learning curve, so you won't sacrifice typing speed while transitioning to a split keyboard.
Split keyboards are my favorite keyboard design. A person can separate the two halves at a comfortable distance and orient the halves at a comfortable angle. With the Kinesis split keyboard, you can also purchase a separate accessory kit to enable tenting and vertical typing. Quite simply, split keyboards offer more versatility than any other type of ergonomic keyboard out there.
