I stole it from my g/f's new iMac since she uses a trackball. So far I'm digging it, wish it was more ergonomical and the side buttons bother me. But it's more precise than the other wireless mice I've used which seem to act with a tiny bit of hesitation which you really notice when you need to be precise in PS or AI. Anyway, the acceleration/speed is just a tad slower than I want it. I just need another 10-20% bump so I can easily zip around my 23" ACD but I don't wanna use USB Overdrive as it cranks the scrollball speed way up & won't let me adjust it. Is there some Terminal command I can do?
