OFF TOPIC: If you have a reasonably newer Apple Mac, there is a patch available to enable 'inertial scrolling' (similar to scrolling on iPhone/iTouch) on your your track pad. I think the new Macs that came out in March/April have this installed by default from the factory.
Anyhow, if you are interested, below is the download link. I installed it and it's a fun little feature. If you don't like it, you can switch it off in system preferences.
