My husband travels all over with his job and I noticed he was still using a mouse with a cord attached. No wonder he gets frustrated fumbling with a bunch of wires whenever he’s working on his laptop. I introduced him to the Microsoft Wireless Optical Mouse. Now he tells me that it’s so much easier handling his laptop without having to untangle wires and cords for on the spot presentations. It’s so small and versatile, you can slip it in your pocket and the usb indicator fits right into the bottom of the mouse so you don’t lose it. It’s one of the best investments I’ve ever made.
