No, ECC memory is a must too. ZFS checksumming verifies and corrects

Right, because once (say) Apple incorporates ZFS into Mac OS X
they'll also start shipping MacBooks and iMacs with ECC.
If customers were committing valuable business data to MacBooks and iMacs
then ECC would be a requirement. I don't know of terribly many
customers running their business of of a laptop.
I do, even though I have a small business. Neither InDesign nor
Illustrator will be
ported to Linux or OpenSolaris in my lifetime... besides, iTunes rocks
and it is the
best iPhone developer's environment on the planet. The bigger problem is
that
not all of Intel's CPU products do ECC... the embedded and server models do,
but it is the low-margin PC market that is willing to make that cost
trade-off.
If people demanded ECC, like they do in the embedded and server markets,
then we wouldn't be having this conversation.
