Both Amazon and Best Buy have the well-reviewed Logitech M510 Wireless Mouse at its lowest price in months. Just $19.99 adds one to your tech array. I'm a huge fan of Logitech products and an even bigger fan of their tiny Unifying USB receivers. My office has one of these in our conference room and I'll attest that the 2-year battery life claim is no joke. If you could use a new wireless mouse, buy this one.
