I own 3 Logitech M570s. For the average user, there's no better trackball on the market. The design is perfectly ergonomic and unless you have some strange need for ultra-precision beyond even the most demanding users, the M570 will do what you need. The M570 has two main buttons, two side buttons and the middle mouse button. The only features I miss are side-press buttons on the scroll wheel, and "speed-scroll" when the scroll wheel spins freely without detents to stop it. The battery lasts very...very long, and the software will even warn you when it's getting low. M570 uses Logitech's unifying receiver, which is not a bluetooth, but it's small and easily stays in the USB port when packing a laptop, or stores inside the battery compartment on the M570.
Finally, consider that Logitech customer support is phenomenal. I have called them when previous products have failed (after many years of heavy use but warranty is up to 5 years on some items) and they just replace them without question, without asking for the original product to be returned.

EnigmaRaptorM570s are good, but up against legendary trackballs like CST 2545 or CH Products DT225 I think it's a poor choice!

gormanI just can't see center ball design coming close to the ease of use of the thumb ball on the m570. I am wondering what qualities you are weighing to catergorize those legendary track balls. Maybe i am missing something. I am however always on the lookout for superior pointing devices, so if you have some compelling reasons i might pick up one of your favorites.

EnigmaRaptorIt's mainly for speed and accuracy. I have an M570 and a few CSTs and an A4Tech, among others, but finger balls are far more precise. The -5W CSTs also allow you to add buttons, so you can put the left/right buttons under your thumb for more convenience, or move them to the right side to use it like a thumbball.

EnigmaRaptorhad an M570 for a month and my thumb hated it. honestly, you don't have much precision with your thumb, but you have much finer tactile control utilizing your other fingers. Thumbs are inherently non-precise, they mostly just curl and allow the ability to grip objects.
