Have you ever looked down at your mouse and said to yourself, "You know, I wish this doubled as a touchpad"? If so, your days of peculiar self-musing are over, as Gigabyte recently launched an intriguing new device called the Aivia Xenon dual-mode touchpad mouse. (Try saying that three times fast!) It's like the input equivalent of a mullet, except this bad boy's all business in the front and the back.
A handy-dandy switch on the side lets you switch between the two modes. It looks a bit oddly shaped (and probably uncomfortable) for a mouse -- in fact, the pictures make it look more like an itty bitty router than anything else -- but the Aivia Xenon sports a 1000dpi resolution and supports several multi-touch gestures when it's in touchpad mode. If you're the presenting type of person, the mouse/touchpad/whatever can operate up to 30 feet away from its base computer and packs in "Aivia Painter software" that allows you to mark up any document you have open.
