I am using the five home screens available in Cyanogen's and Dwang's ROMs for different categories or related categories of apps. (I recently switched to Dwang's and find it very stable and zippy.) Here are the screens from left to right. The middle one is the default home screen.
Leftmost: system administration and networking

Center-left: multimedia

Center: communication and information management

Center-right: news and reference

Right: games and tools (and dictionaries)

Other apps or activities without screen shortcuts
