How can any self respecting speed freak like myself not make mention of a mouse accelerator or two. That is something that has always driven me nuts about OS X; the maximum mouse speed is just too darn slow. Back in the day when I was running OS X 10.2 on a fruity iMac with a puck mouse, I found a great little preference pane app called [USB Overdrive](http://www.usboverdrive.com/) (now supported by [Senlick](http://www.senlick.com/)). I used [USB Overdrive](http://www.usboverdrive.com/) faithfully up until a few weeks ago. It was great for making a multitude of USB devices go stupid-fast, but I only use one USB device, my mouse. What I wanted (with the onset of carpel tunnel syndrome) is a fast mouse with very fine accuracy and acceleration controls.
What I found was [SteerMouse](http://plentycom.jp/en/steermouse/), another preference pane app that allows for finer tuning of the mouse tracking speed and sensitivity, etc… it also allows for detailed button programing (up to 16 if you like). Though [SteerMouse](http://plentycom.jp/en/steermouse/) is by no means worlds apart from [USB Overdrive](http://www.usboverdrive.com/), I was pleasantly surprised with it’s interface and feature set and think I will stick with it for some time to come.
So just how fast do I have my mouse set? My mouse travels at about 180 ppi. To put that into perspective for you, I can go from adjacent corners on a 23″ HD cinema screen by moving my mouse little more than few inches; just the flick of my wrist.
