While "ergonomic mice" have been hogging the limelight recently, the fact still remains that there was one peripheral that was, is and probably always will be the gold standard against which all ergonomic devices are measured: the trackball. The lowly trackball really doesn't get as much credit as it deserves and most people think of "cheap arcade games" when they think of examples of trackballs. This really is a crying shame as nothing is more ergonomic and nothing is easier to use for extended periods than a good trackball. When it comes to manufactures of trackball's one manufacture really stands above the rest and that manufacture is Logitech. Logitech has been making kick ass trackballs for decades now and their latest the M570 is not only an ergonomic trackball it adds additional buttons and useful wireless abilities into the mix. So how good is this new Logitech M570 trackball and does it live up to Logitech's sterling reputation? Read on to find out in my full review.

The Verdict:
If you put in the time and effort it requires to master a trackball, the Logitech M570 will be really reward your time and effort. To put it simply, this is one of the easiest, most precise and all round best trackball I have used in a long time. If you want an ergonomic input device this is the device you want.

The Good:
+ Extremely comfortable
+ Extremely forgiving for beginners, yet highly rewarding for veteran trackball users
+ Long battery life
+ Great looks
+ Lightweight design
+ Storage built into the battery compartment for the Unifying dongle

The Bad:
- Right handed device only
- Learning curve can be daunting for first time trackball users
- Slick surface too slippery for smaller hands
- Forward & Backward button locations does take some getting used to
- Click wheel is loud and less than perfect compared to most Logitech mice
