That sounds like a really great feature! I was looking at a laptop that is built using similar tech features the other day, but I forgot to bookmark the site and can't remember the name. It had it's own OS (not sure how they done that, think it's Ubuntu based) and it had features like kill switches for the mic and webcam.

I'll have to look into Blackberry again when the time comes for an upgrade. I'm almost waiting for something a bit more "special" to come along. :-)
