Here’s a prompt from Adobe that asks me to update the Flash Player on my MacBook Pro:
In general, I’m used to an application informing me that a new version is available and I should download the update just because.

Expose is a feature in Apple OS X that allows you to see all of your open windows spread out nicely in front of you. They look as though they are on your desktop, and then you can click which window you want to take the focus back to. Here is an example:
