I'd decided to cut the cord after the predecessor stopped working altogether. That wasn't a cheap mouse and I wasn't about to let Logitech win ;-) (Given the options were pretty much forking over more $$$ to them or fall back to some no-name corded rodent.)

And there's one more nasty trick Logitech plays should you decide to look at cordless options: they heavily promote their Unifying receivers which can handle several peripherals. If you buy a combo, you'll get that Unifying receiver, but should you ever need to replace it and one piece of the combination*, you'll likely end up with a Nano receiver which cannot handle multiple devices.

* We used them in classrooms at $employer^1. The mice and receivers had a strong tendency to grow legs. We ordered a gross of replacement mice, same model number, and got useless lumps of plastic as the receivers couldn't pair with the remaining keyboards. All sad really, as we decided on Logitech because the battery life is miles ahead of anything else we evaluated.
