I finally got Tiger today. Installing it was okay, though Apple's Mail app kept crashing due to some modifications I had done in the previous version about six months ago. I've got the problem solved on my Powerbook and will hopefully solve it soon on my iMac.
The app itself is very cool, smart folders are awesome easily organizing about three hundred email messages. Dashboard is sweet too, as is the Spotlight feature. I'll have more on it later, but I just thought I'd give a shout out to all my Tiger peeps.
