Tried to sign up for newsletter and offers and kept getting:

"An error has occurred.
An error(s) has occurred while trying to subscribe you to our contact list:

That was using Firefox. Tried again with Omniweb and sign-up worked.

All very odd.

Looks like P9 is ok for my G5 PowerMac; PP2012 mentions Intel chip preferred. After that I reckon all upgrades will be Intel not PPC.
