How are you using Spaces?

Hey guys.

I've been playing with spaces lately, and got curious as to how others are using it. Right now I'm using the standard configuration of 4 spaces with my two screens (MacBook screen and 22" monitor).

The way I have it set up right now the applications on the MacBook screen are static. In other words, both Adium and iTunes are on that screen and are set to show on 'Every Space'.

So, the 22" Monitor is where all the cool spaces action happens...

Space 1: Main Safari window(s) + Finder
Space 2: iCal, Mail, Address Book
Space 3: Photoshop or Light Room
Space 4: Any other separate project

I've started to get pretty comfortable with the idea of having a few separate work environments and I have found that less on screen clutter lets me stay more focused on the task at hand. My one complaint was that moving an application (say an extra Safari window) from one space to another was a bit of an inconvenience. This has been solved by Warp for me. Simply click and drag to a screen edge... It is both intuitive and practical. About the only other issue I can come up with now is I wish there was an option to only show my primary screen when hitting F8.

So, back to my primary question... How are you using Spaces?
