FWIW, going from Lion to Snow Leopard would be a downgrand. Simplest thing to do is restore the bootable backup/clone or Time Machine backup of your previous Snow Leopard volume. Hardest would be to boot with the Snow Leopard install disc, erase the Lione volume, losing all of your documents, settings, and 3rd-party apps, reinstalling SL and those 3rd-party apps, and resetting your settings.27" i7 iMac 10.6 , Mac OS X (10.7), G4 450 MP 1.5 GB RAM w/(10.5.8/10.4.11/9.2.2)

Written just for you (ok it's a paste)
Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
Disconnect other drives except the backup drive as to avoid any mistake.
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire disk of ALL DATA. (warning, everything will be gone and not recovered, OS, programs, files, Windows etc all gone.)
Note: You might want to hold c and boot off the 10.6 installer disk and use Disk Utility to format the new blank external drive instead of using OS X Lion that's hosed. Then reboot into Lion and copy files, be safer that way perhaps.
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP there, don't install OS X yet.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same drive name as before, and click Erase...
(note: if you want to "scrub" the drive of old files that haven't been overwritten yet, then use the Security Option > Zero Erase, takes a lot longer)
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly recommended.
A lot of people use a Carbon Copy Clone of their boot drive to a new HFS+Journaled external drive (used only for this purpose) as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.

I actually have uptodate Time Machine, however I'm thinking that a fresh install might be a good idea anyway to clear out the apps that I don't use anymore.

Ha ha, seriously though that is fantastic - I am really looking forward to getting this Mac back to Snow Leopard.
I don't mind the new features - even learning the "natural" swipe direction was fun - but what they did to Expose is a deal breaker.

Is that the same as "Mac OS Extended (Journaled)"?

Thank you so much for that advice, it worked perfectly. And, my Time Machine backup worked like a charm.
Exposé is such an improvement on App Exposé (and Mission Control).
The upgrade from Lion to Snow Leopard was definitely worth the (minimal) effort.

Does anyone connected to the development team read these forums?
Expose & Spaces were such a useful [and much loved] part of the OS- why such a huge backwards step? And why not remedy the situation– are they just being pig– headed, or do they really feel they've made a real improvement here? It almost seems as though the OS developers are out to spite us customers.
