Matt, .... if Sun is in troubles the HP Integrity line is not in any better shape with Itanic (despite how you are picturing nicely a well known dieing processor). Sure Intel has tons of money but, if you notice, they are putting all of them on Xeon not on the big (dieing) brother.
Intel (and HP) are fully committed to Xeon/Proliant ..... they are still doing Itanic/Integrity simply because they can't quite that market w/o loosing their face... but it's clear they are both disinvesting in that space.
Move onto the next religious war.
