Background information on development of SteelSeries Ikari mice

“When a company mentions DPI in the same sentence as precision, or anything else regarding better tracking, it is simply bullshit. First of all the term DPI (Dots Per Inch) has nothing to do with mice. It’s an expression from the printing world and shouldn’t even be used to describe mouse movement. DPI is meant to describe the fact that for one inch of distance you move your mouse on any surface, the equivalent number of counts are sent to the PC - resulting in movement on your screen. The correct term for this is CPI (counts per inch).”
