I think you know that I'm a solid linux fan so do take that on board

IIRC one of the concerns is "what if it all goes wrong".

How many people do you know who can help if your ZFS system goes titsup?

Are all the nice ZFS tools ported/GPLed? or just the cli ones?

What can ZFS do for you that you can't do with other systems?

Seriously - as a home user, what do you need?

Snapshots are cool - essential if you need to backup a 24x7 operation. Now weigh up the complexity vs the risk they introduce.
