Armed with the Razer Copperhead, hardcore gamers can no longer blame ignominious defeat on the !@#$% mouse. Among its foe-fragging features is a first-ever tracking precision of 2,000 dots per inch and a one-millisecond response rate for the fastest and most accurate moves. It's also the only mouse to dedicate 32 kilobytes of onboard memory to saving different settings for different games, so you can go from the precision-demanding first-person shooter to a more casual role-playing fantasy without messing around in a control panel. Add in seven programmable buttons, an optional adjustable weight system and an always-on laser for instantaneous response, and you've got the most butt-kickin' mouse on the market. $80
