    I'd love to know why they think lasers help.

    Eh? The Roccat Kone Pure Optical doesn't use lasers; the entire point is that it uses an LED-based optical sensor instead. The Roccat Kone Pure uses a laser, as the article makes abundantly clear.

    As for why lasers help (or hinder): a laser-based light source on an optical sensor allows for much finer-grained accuracy. Just look at the figures: the Roccat Kone Pure Optical, with its LED-based light source, tops out at 4,000dpi; the Roccat Kone Pure, which uses a laser-based light source, hits 8,200dpi. That's more than double the resolution.

    Some don't like the 'feel' of a laser-based sensor, however, and would prefer the old-style LED light source. It's for these that Roccat has built the Kone Pure Optical.

    Sure, absolutely, the question was more "why does it ever make a difference". I appreciate they have larger resolution figures, but it isn't clear to me why that's necessarily associated with the character of the illumination. Modern optical mice frequently use something like a 4x4 or 8x8 pixel "camera" looking down at the surface on which the mouse is running. I suppose you could take the position that the finer light source of a diode laser casts sharper shadows from the details on the desktop but the resolution of the thing is ordinarily more down to the detector than the emitter.

    After all, a diode laser pretty much is an LED, just one about the size of a bacterium.

    The reason the DPI is greater with LASER mice is because of the rectilinear quality of a LASER beam compared to the highly divergent nature of all other types of light sources, including non LASER LEDs.

    Back to the roots.

    Next year, a direct-kinetic-driven mouse for those hardcore gamers out there...you know, with a rubber ball in it ;-)

    As a low sensitivity gamer, I've never been satisfied with the tracking of a mouse with a laser sensor. Optical all the way!

    Voice command is the way to go:
