I don't know about you, but changing batteries for my wireless keyboard and mouse accessories was never that big of a deal. Sure, less often was better; but never was there a case where I'd wish that my input devices could go longer with a fresh set. That said, Logitech today announced the Wireless Desktop MK710, which suggests that there are people who are annoyed with having to swap batteries in and out of their mouse and keyboard.
On the surface, it's just another keyboard and mouse combo. In fact, there's nothing outstandingly fancy about it on first impressions; but digging a little deeper, we find that this thing will run up to three years on a fresh set of batteries.
"No one thinks about changing batteries until they have to, but when that time comes, it can stop you in your tracks," said Rory Dooley, Logitech's senior vice president and general manager of the Control Devices business unit. "With its industry-first three-year battery life for a combo, you might just forget the Logitech Wireless Desktop MK710 uses batteries at all."
Looking at the fine print, we find: (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.)
I always keep a charged set of Eneloops around in case of dead batteries, but having long-life devices such as Wireless Desktop MK710 is both less inconvenient and less harmful to the environment.
