Best keyboard for writing books, and not getting carpal tunnel.
As a writer, I have become absolutely spoiled by these ergonomic keyboards. It improved my writing speed, and the design completely cancels the ache in my wrists on the straight keyboards. I wish they were still making them but as long as I can find them in excellent shape on eBay, I'll keep buying them when they wear out (or get tea spilled on them which has happened before!). Once you get used to the layout of the keys, you'll never go back.
