You should ask yourself if you want bluetooth or regular RF wireless. Then, ask yourself if you plan on using the mouse in one place all the time, or traveling with it along with a laptop. I have a travel mouse from Microsoft that I'm pretty happy with. You should note that travel mice usually have AA batteries instead of recharable, so you can quickly purchase batteries while on the road instead of lugging a charger around (and even then it gets around 4 months per battery). but be warned, travel mice (which are typically smaller and have snap in/out usb dongles) have terrible RF range. If your mouse is more than 3 feet from the dongle, you get cut outs.
