I'm a lifelong Mac user, but I use a PC at work and that means using Excel and Word a lot. Whenever I work from home on my Mac I always have a slight bit more difficulty in selecting the cells I want in Excel and I do attribute this in the slight differences between how the Mac mouse and PC mouse work. I've used USB Overdrive for as long as I can remember but I only started thinking about what settings would give me the same mouse movement as a PC on my Mac. Anyone have any help on this? I am mainly interested in what Speed and Acceleration setting you have to best mimic a PC. I currently am using 400 dpi and 150% accel.
