My last Intel box (Northwood 2.8 GHz... no Prescott or later for me thanks) is now my LAST Intel box.
Of course, I and a few others were saying this a year ago, but they called us paranoid.
"A trusted resource is one that has the potential to break security." - The Pentagon, referring to the whole concept of trusted resources, computing or otherwise.
Think about the above statement. You will soon be trusting your computer (and by extension, MS). Previously,
there was no need to trust it, because it couldn't break your security. And frankly, I
don't trust or want to trust Microsoft or Intel.
Trusted Computing is, for you, LESS secure than what we have now.
For Microsoft and Intel, it's more secure, but I'd rather have ME be in control of my data, not Microsoft and Intel.
