Genuine computer-security guru Bruce Schneier mentioned one of these videos in his blog (here), but apparently couldn't bring himself to comment further.
I covered security products for Microprocessor Report, and I've been following the subject for about 25 years. I even won a CNET-sponsored contest by writing about hardware-based computer security and got a free trip to speak at Esther Dyson's PC Forum 2005 (see the announcement here; the speech I gave at the conference is here).
But wow, I'd never have considered hiring a back-up band for my performance there even if I could sing.
Anyway, the truth is that Intel doesn't really deliver much in the way of hardware-based security features. An Intel-based system isn't any more secure in practical terms than an AMD-based machine. Maybe if they'd spent the no-doubt considerable fee for the talented Mr. Guest on engineering work instead, they'd have something they could really sing about.
