Spaces is a new feature in Leopard, and it's useful for the folks with small screens who like to run a lot of applications at once. Spaces lets you toggle multiple desktops where you can drag and drop open application windows. You can keep it simple with two, or bump it all the way up to 16. Power users can also set up applications to always open up in a certain space, keeping screen real estate under control.
