Logitech Introduces Ergonomic, Long-Lasting Wireless Combo MK 520
At a glance, the overall design seems rather simple; there's no split design for ergonomics or anything like that. But there actually is a concave design element along with rounded edges and the company's low-profile Incurve keys, which are said to position your fingers properly and make it easier to glide from key to key. It also has an unheard-of three-year battery life, and can incorporate one-touch media controls so you can mute your computer or skip to the next song, instantly, without using your mouse.

The full-size mouse isn't a gamer's dream come true, but it looks rather comfortable for the average desk worked. It's built to be used in either hand for long periods of time, and offers a one-year battery life and smooth tracking on nearly any surface (including most everything except glass or a mirror).
As with most of Logitech's new wireless gear, this combo also utilizes their new Unifying receiver, which is a tiny USB plug that's small enough to remain plugged in and provide range of up to 10 meters. There isn't a price being made public just yet.
