Logitech just unveiled 2 new mouse technologies geared at gamers. To eliminate the lag time & accuracy issues usually associated with wireless mice, their new G703 & the G903 models feature Lightspeed, which uses “end-to-end signal optimization” to cut the lag in signal speed down to 1 millisecond. And to keep your mouse charging at all times, they created Powerplay, a wireless charging system that uses magnetic resonance to keep your mouse constantly powered up.
