At first when I seen this I thought why choose such a poor company such as McAfee... (no need to explain further right?) but then it dawned on me that after reading that Intel bought them that was the reason why! Wonder how cheap Intel got them for, because can assure you that this must of been the main motive. Good move for Intel, bailout for McAfee who will be under huge pressure to perform for the new owner. This is a good step in providing more security at a hardware level, but for how long we do not know surely! Some point this will either be flawed, or a way will be found out to bypass such a thing then the whole cycle starts again.
In all things IT between the good and bad, it's a never ending perpetual cycle going back and forth.
