Time to purchase gifts or just upgrade your computer? Why not add a Philips Wireless Optical Mouse.Hey, why not add 2! Makes a great gift. No wires, no tangles, no hassles. Not only is it optical, not only is it wireless, but it has an RF field range up to 5 feet (which is 1.5 meters for your metric buffs). In case you are wondering it supports 98/ME/200/XP/Vista. Yes, Vista. So I hope we asnwered that question.One retails for over $20.00. Thing Fling's price for 2 is $19.99.
