High definition is the motto of today’s electronics. Everything has got to be high def: from your home theater’s TV to the LCD monitor hooked to your PC to – who knew? – the mouse you’re using right now. The newest gaming mouse from Logitech, the G9 model, reaches an impressive resolution of 3,200 dpi, breaking the 2,000 dpi barrier of his G5 precursor and similar models on the market. It also incorporates the highly praised scroll wheel from Logitech’s VX Revolution line. With two different interchangeable grips the mouse is just as useful for gaming as for regular desktop use.
