OCModShop published a Logitech Wave Keyboard review.
Quote from the review: "There have been many, many, many different keyboards for personal computers over the years. Ergonomic boards, tough boards, media boards, gaming boards: boards that climb on rocks... and there have been a few that many people like, but they become discontinued and obsoleted in favor of the company's next generation products. An answer to the super-ergonomic keyboards are the new "wave" type of keyboards, which appear to be a hybrid between a regular flat keyboard and ergonomic. The keys are usually curved so your fingers don't have to reach so far to hit the top row of keys, and some are slightly cupped to cradle your finger's natural position. Logitech enters the fray for your fingertips with their new "Wave" keyboard. "
