I miss Snow Leopard! I am currently using Lion, but it is slow on my 2008 MacBook. I wish I could go back to Snow Leopard, but my optical drive has stopped working, making me unable to install it again. And I didn't have time to figure out how to install Snow Leopard without an optical drive...

Get another Mac with a working optical drive, image your SL disc to a USB drive, and boot from there...

Well, that's the problem. I couldn't find another Mac to do that...
