Computer mice have seen their share of practical upgrades over the years scroll wheels, wireless tech, and optical tracking come to mind but are we ready for the dual-cursor mouse? It appears to work like this: you have two cursors on the screen, one red and one white. You operate the white one normally, but when you want to point with the red one, just click and hold the side button with your thumb. Why would you ever need two mouse arrows? That's the hazy part, but you could theoretically use it to select two separate groups of folders or files simultaneously. For gaming, the two arrows could designate, say, two different weapons in each hand for a first-person shooter like Doom. The mouse, Model DCT-DPM1, is made by Digital Cowboy, the Japanese-based creators of the video iPod privacy filter.
