Out with Virtue, in with Spaces
Spaces makes way for the masses.

Leopard continues to impress. As many of you may already know, reports are streaming in from users who have had their hands on the new operating system. The consensus? While not ground breaking, Leopard is a good solid update and worthy of the hype. One such reason is Spaces. Multiple desktops have been widely accepted and utilized by the computer literate and savvy. However, the application has since gone mainstream, and even the most basic computer user is benefiting from the convenience and efficiency which multiple desktops offer.

Spaces offers a unique combination of short cuts. By pressing f8 you may pull up your grid, allowing you to drag and drop windows to and from any space you desire. Spaces also offers application assignments, allowing you to specify a unique desktop in which to open an application.   Another neat feature is an “Every Space” option, which allows you to set an application to be available in all spaces.
