As compared to straight keyboards, there are 3 features that set these new curve keyboards apart. These features include a wave key-frame design, a U-shaped constant curve, and a cushioned, contoured palm rest to help users achieve a new level of comfort while working.
“With the increased awareness and demand for comfort in our day-to-day lives, Logitech’s new products offer a timely solution,” said Denis Pavillard, vice president of product marketing for Logitech’s keyboards and desktops. “According to a study at Harvard, for Logitech, the average person types approximately 2 million keystrokes every year. That’s equal to 200 hours of typing. The Logitech Wave Comfort Design will delight people by offering the perfect balance of comfort and usability.”
The Logitech Cordless Desktop Wave keyboard-and-mouse combination is expected to be available worldwide beginning in late August and will have a suggested retail price of $89.99 (U.S.). The corded Logitech Wave Keyboard is expected to be available worldwide beginning in October and will have a suggested retail price of $49.99 (U.S.)
