i still dont know what ZFS is even after reading the Wiki and looking at other posts
It's a file system that embodies all benefits of HFS+ (our current file system) + more...lots more.
I really hope Apple+Solaris get this sucker to work for boot disks because file systems are one of those things that nobody understands or wants to understand and hardly anyone's gonna benefit from it until they buy a new computer (who besdies geeks actually care about the file system? Nobody...although they should.)
If Apple can make ZFS the default file system and make Time Machine and File Vault tap into the snapshot and encryption features of ZFS...oh boy.

Exactly! Imagine having an 8-core Mac Pro with ZFS.
Visualize no silent corruption. Realize that RAID 5 will protect data loss but not data corruption.
Visualize adding storage at anytime without having seperate drive icons littering the desktop.
Visualize redundancy...lose data if can be replaced from parity information
Visualize encryption at the drive level. Suddenly Mac Vault isn't such a bad thing.
Visualize compression. Imagine your joy when you compress your hard drive and regain Terabytes of storage.
Man this is going to be a boon for creative types that want to just create a nice big pool of storage.
Weeeeeeeeeeeeeee no more volume management!!!!
I'm not getting how this works. It sounds as if when you plug in a drive you get a single amount of storage which implies that files are split between drives without you knowing which one is where.
You don't care right now that your files are split and scattered all over a drive, do you?
I sure don't. I'd rather the OS/fs handle that mundane task. I'd love to view everything as a contiguous block of storage yet maintain the ability to manage some of the higher level stuff.
Man I really can't wait to see how Leopard evolves. This stuff is great.

I think people are worried that if one drive fails, half their files will become corrupt/destroyed.
What they don't understand is that even if the two drives were considered seperate and even if one had control over which files go into which drive, there's no way to know which drive will fail, so the same situation occurs...one loses files. Maybe less than half the files, but maybe more than half. Depends how the person decided to store his files. It's a 50/50 gamble.
They also don't realize that ZFS can detect the symptoms of a failing drive...the file system will attempt to move files off the failing hard drive and onto the good hard drive. And because of this, ZFS is the superior solution.
I'd rather have a file system that pools hard drive capacity and that attempts to stuff all the files onto the good hard drives when one of them is failing than many seperate hard drives with a file system that is too dumb to save the files from the failing hard drive.
Sounds a lot like "I'd rather be rich than stupid."
If people want to visualize the concept, they should picture the way RAM works. Adding more RAM to a computer simply pools the memory capacity of each RAM chip (well, the OS does it) and makes it available to the OS and all apps. There's no segregation anymore...nobody can assign a particular RAM chip's memory capacity to a particular app...and if one RAM chip fails, chances are the user will see a the wonderful kernel panic curtain of death unfold before his eyes and some data will be lost. It's the same for hard drives.

Yup, nor should you care.
