![]() It supports both Bluetooth and a 2.4GHz connection via a USB dongle, and it's easy to switch between them at will. In terms of connectivity, the Expert Mouse Wireless gets full marks. ![]() They are worth considering, however, and I'm still holding out hope for a design tweak or new functionality that bridges the gap. These issues are endemic to all trackballs, not just the Expert Mouse Wireless, so I'm not criticizing Kensington here. If you are in one of those groups, a trackball could make sense for day-to-day computing to keep repetitive strain injury in check, but it isn't suitable for high-performance tasks. If you aren't a gamer or making digital art, your speed and accuracy will improve over time to the point where the trackball becomes second nature. The need to be accurate at high speed is rare unless you play video games or edit art professionally. It's easy to roll the trackball accurately over short distances and to make fine adjustments, but long rolls-like what you'd use to travel across a dual-monitor setup, for example-are generally imprecise and require corrective motions that require more deliberate thought than a standard mouse.
