So, to the people concerned about security issues with this technology, you do realize the entire reason Intel made it was to reduce the ability for third-party users to access your system either remotely or directly? It isn't so important for every day users, but it is a major selling point for businesses. As for the government, Intel or Microsoft stealing your data, as these organizations have virtually unlimited resources at their disposal, I don't think any of them would bother targeting this software when they have other methods of getting into you system if for some reason they really wanted to.
@turkey3_scratch: I'm not entirely sure what security methods Intel is using with these, as they might have changed from previous generations, but there are several ways hardware can be used for security tasks. Sometimes it is just altered firmware that adds additional protection to the hardware, or it could perform some type of actual processing, like running the AES instruction set for accelerated encryption of files.
