Appreciate your elaboration. Seems mine is a no go for mobile, then, if it&#x27;s Intel chips and such. Embedded-style computers for trusted part are still a possibility. I&#x27;ve seen a card computer put into a laptop for a coprocessor. Hardwire in a KVM-style switch so the coprocessor can be the main processor when necessary. It&#x27;s naturally removable. This lets key stuff be done on trusted component, safe storage, and even checking of untrusted stuff with what techniques are available.<p>Just gotta have something that does computation &amp; storage that will not lie to its user.
