This Elecom mouse might just have the edge over other devices, because it can swap to nine different devices. A button located near the scroll wheel will let users swap between laptops, desktops, or anything else that relies on a mouse. It will display a simple LED number to show you which device you're connected to.

Its $100 price tag though, seems like a deterrent for the comfort of being lazy to connect them wires. What do you think?
