Imagine that your mouse cursor is sitting near the bottom left of your screen and needs to instantly jump near the top right. Would it be simpler for your brain to gauge only the distance your hand needs to travel, or the distance that your hand needs to travel along with the speed at which it needs to travel? The answer is that mouse acceleration makes it much much harder to gain precise mouse movements during gaming. So we need to turn this darn thing off.
Pfff this is a groundless speculation about brain.
Maybe his brain is that slow, but some acceleration is pretty much natural for normal human being. To prove my point, open a huge image in Photoshop, zoom in, and play around with the "Move" tool. If you haven't used Photoshop previously, you'll see that it takes maybe half a minute to become proficient with the "Move" tool and easily get from one part of the image to another.
Besides he should really tell that to a long time Mac user who uses the default system acceleration. The curve there is much more steep than the accelerated curve in Windows, and this causes slow movements hardly move the cursor while faster movements teleportate it through your screen. This sucks (and it's quite funny that none of Mac sceptics ever mention this in their rants) but the fact is, most Mac users somehow get used to it and become very precise with their mouses.

Mark Cranness made this fix for
old games which force "enhanced pointer precision" (EPP). If you don't use EPP on Windows this certainly becomes a problem, so the patch replaces the EPP curve stored in the registry with the linear curve.
If you don't play old games which enforce mouse acceleration, then you don't need this.
By the way to have an idea of what the EPP curve looks like, visit the viewer I made together with Mark a year ago:
