I just pray it's seamless and invisible. McAfee is usually the first thing I remove when I get a new PC... it slows things down to molasses and can only refute last year's virus. I must say, I still see INTC's AM of McAfee to be boneheaded stupidity.
You will probably be very surprised in a good way. When you bind the protection down very close to the bare metal you get much more secure solutions without all the bloated SW overhead that you are mentioning.
With all of the cybercrime and state sponsored hacking going on, this may have been one of the more brilliant strategic moves in quite some time.
People will demand better security, and Intel is taking this seriously. And their strategy will enable them to turn it into an opportunity that will differentiate products based on iA technology above all others.
