While I, too, would love it if we had a corded version just so I don't have to switch batteries, I see that many people here are having problems because of bluetooth performance. I thought I would add my experience that I've recently been using several wifi routers with DD-WRT and Tomato firmware on them, and they allow you to enable 'Bluetooth Co-Existence' mode on the wifi router. In at least one example, this solved a problem where my magic mouse's behavior had been terrible until I made that change. Otherwise the mouse has worked great for me in several scenarios. I would love it if someone figured out a hack, though, that fed it power through a USB cable..
