Simply, I love Spaces. Allows me to have an individual pane for each subject I may be working on, usually college work, eBay business, music, one for just surfing the web and another for mail and calendars... I'm deeply curious as to how others use Spaces and how you've got it configured for your personal ease of use. I've tried having a bunch of spaces like 9 or so but sometimes I think that's just too much, though useful. Since I've had OS X Leopard I've stuck with 4 spaces. One for music solely, another for internet browsing for just killing time or researching school work, another Space for Pages/Word and another for Mail. Or interchange their use and select a Space for online business work. Or financing my accounts. I love Spaces, it works well to switch to a Space set up with Pages and research quickly if someone gets near when I'm actually just killing time on Digg.com Post any tips, suggestions you may concerning Spaces and how to enjoy it further and implement some useful techniques. For example, I've set up a few apps to open to corresponding Spaces only so all my work under that category stays within that space.
