Oh yes, that up there is Logitech's newest Wireless Trackball M570, which apparently caters to an "overwhelming demand of dedicated trackball users." Well, we'll be damned! At this point, we'd figured that trackballers would have switched over to an MX or something by now, but we do have to say the new sculpted shape is mighty comfortable, and if spinning a big blue ball to navigate the desktop is your thing it doesn't seem like a bad deal. The $59.99 peripheral will be available immediately, and packs 2.4GHz wireless and a small USB Unifying receiver that tucks into the bottom of the mouse for safe keeping. Logitech sent us one to play around with, and though we're not exactly the most nimble at using the trackball to jump from window to window, the scroll wheel felt calming enough and there are two back / forward buttons to get you from tab A to tab B. Guess we really have to hand it to 'em for sticking with what works.
