There are plenty of fancy keyboards on the market but not all of them are designed to go easy on your hands. The Kinesis Freestyle2 can help. It is a modular, ergonomic keyboard with parts that you can separate up to 9″. The Kinesis KB820 allows 5, 10, and 15 degrees of tending.
The keyboard has a standard layout with hotkeys, a numeric 10-key pad, and cushioned palm support. It is compatible with Windows and Mac computers.
