I have it installed on a test machine at work, and it all works perfectly.

We tried it with Vista and that completely killed it though.
Blatted the machine after that and put 10.4 server and XP SP2 back on it again, and again its working fine.

From what i have read it seems to be a bit 'beta -ish' on the intel laptops.
Seems to kill the EFI partition for OS X. Which isnt a good thing.

But this is 'BETA' software. It should never be put onto a production system unless you are doing tests in a live environment, and even then you should be doing it on a system that you can rebuild easily.
