2. Better protection against security threats on mobile devices. As smart phones, TVs, and even cars access the Internet more and more, worry grows that security will become an increasing concern in those products.

It's murky just how extensive the security threat is to mobile devices in the first place.

It's easier for malware writers to attack Windows PCs because they're all running on the same operating system—new code doesn't have to be developed for every product. The mobile space is a different world, running not only on a variety of processors but on a variety of software platforms, from WebOS to Android to Windows 7 and more. The bottom line: It's much less "lucrative" for malware creators to have to hit that many different operating systems, so there might be fewer problems at least for now.

2. Will free software be impacted? Our tests of security software (available to subscribers) have shown that free anti-malware programs work fine for most people. Many consumers have gotten used to free anti-virus solutions, and even Microsoft has gotten into the act with its gratis Security Essentials. If Intel raises the cost of its processors because it can now claim "built-in security," the advantage of using free software could disappear, or even become unworkable as conflicting security solutions butt heads.

Intel has faced its share of anti-trust issues in the recent past, both here and in Europe. The specter has also been raised now. What happens if Intel makes consumers buy software before they can turn on the hardware security protections? And how will competitor Symantec react if PC security is hardwired into the chips, leaving consumers no other choice?

It's possible that Intel will largely focus its new security efforts in the corporate world, for example offering protection for cloud computing. We'll continue our coverage as the story develops.
