Leopard Ships this 26th
You can do the upgrade which keeps your settings and files intact and just replaces the OSor
you can do a clean install which is basically a format and install. With the clean install, you probably would want to make a backup of your files so you can put them back after the install. Then you will need to tweak your settings again.
Seems like the methods are about 50/50 as far as users go.
Ah great, thx to you and also iGo.

WHOA, I pre-ordered my copy of Leopard with the free shipping for $129+tax. TO MY SURPRISE, they are shipping it overnight, and it is expected to arrive 10:30 AM on the 26th!!!
BOOYA. Leopard before 6pm on the 26th. Stoked.
By 10:30 via Fedex from Ontario, CA. Mine shipped today too...woohoo!!!!
Just got my shipping notification... Will be here by 10:30 AM tomorrow. I'll be at school, though, so I have to leave one of those FedEx "I'm not here" slips.
First post updated, with link to AppleInsider's Leopard Gallery.
Recieved Leopard Family Pack via Fedex.
I'm going to the Apple Store after work because my son is first in line again. He was first in line for iPhone and received a lot of press.
Then he and I will install Leopard on my MacBook, his MBP and PowerBook, our Mac Mini, and then the 5th install will wait for Thanksgiving Break when my daughter will be home with her PowerBook.
Happy!!!
