Sick of buying batteries for wireless desktop devices? Me too. I even ditched them and went backed to the wired variety. Now, Logitech is promising us three-year battery life in the Wireless Desktop MK710.

It's going to be a while before we can report on the claim but get back to us in May 2013 to see if Logitech pulled it off. According to the company, "Battery life of Logitech keyboards is based on a calculation of an estimated two million keystrokes per year in an office environment; battery life for Logitech mice may vary based on user and computing conditions."
Anyway, you can buy it for $128 later this month.
