What the heck is going on here? First there was a guy freaking out over a double rainbow and now thereβs a mouse that pivots. I have no wordsβ¦ Ok, I do. π SmartFish has introduced a new spin on the ever present mouse. The ErgoMotion Wireless Laser Mouse that features a patented pivot base that allows the mouse to move with your natural hand and wrist positions, which helps prevent RSI (repetitive stress injuries). The ErgoMotion can rock forwards, backwards, left and right. Since it has been designed with a symmetrical shape, itβs also good for left handed users. Itβs available now for $49.95. So, what do you think? Is this better than a trackball?
