What would be really magic is if Apple improved the horrible Mac OS X mouse acceleration curve.

You know - the way that as you move the mouse around at slowish speeds the pointer crawls around the screen terribly slowly, until you move the mouse just fast enough to pass some "magic" threshold whereby the pointer suddenly wakes up and darts across the screen.

There is a ratio between mouse-movement and pointer-movement. In Mac OS X it this ratio appears to change in at least one very obvious step. The problem appears to be at the threshold which marks the change between "the user is moving the mouse slowly and wants pixel-precision" and "the user is moving the mouse at a moderate speed and wants to move around the screen". On hitting this threshold, the ratio between mouse-movement and pointer-movement appears to change abruptly making it annoying and unpredictable. The ratio should vary continuously so that the change in ratio is not sudden (this means the ratio will need to take non-integer values).

I don't think it's a problem of my mouse or anything that can be fixed with the standard mouse speed settings, although it can be fixed with third party utilities. At least the large trackpad on the MacBook is really superb (certainly compared to the one on my Windows laptop) so I abandoned trying to use a mouse on my MacBook and just use that.

Anyone know if this is improved in Snow Leopard or with the Magic Mouse?
