Thanks, Scottsdale! I decided to go for it! I have to say it was a good (albeit, lucky) decision for me! I customized the install and it completed after about 45 minutes (maybe a little less time). I was surprised that it left everything intact... I thought I was going to have to install everything, including my data and applications. It looks like it just updated everything and it seems that it all works and just as snappy. I ran a Geekbench and it went from 2533 in Leopard to 2509 in Snow Leopard. I am sure that the numbers fluctuate. I am not sure what I did wrong to miss the "clean install" option; however the end result works for me. The fans went on for about 5-7 minutes full blaze after I rebooted, but they went back to normal. I have to say I am very happy with Snow Leopard... so far!
