My wife needed a new mouse for her notebook, she wanted a wired one. But I felt that the act of constantly curling and uncurling the tiny strands of wires might have contributed to the fact that the mouse died. So I said I was gonna get her a wireless mouse.
So I saw this Logitech wireless mouse that was rated for 15 months battery life. If it doesn't, then I'm not gonna hear the end of it from my wife.
So this post will be a note that tells me how long the mouse will last.
