Logitech is contributing to the flood of gaming peripherals at E3 with three of its own. It's updating its G903 Lightspeed, G703 Lightspeed and G403 gaming mice with the same high-precision 16,000DPI HERO sensor you see in a number of its higher-end models, plus a few other useful tweaks. The refreshed G903 (above) shares the familiar low-lag wireless design and plethora of buttons, but the sensor's improved efficiency gives it a much longer 140 hours of claimed battery life versus its predecessor's 32. You shouldn't have to charge it nearly so often, then.
