Interesting offering, but truly needed?
I can get a generic laptop at Best Buy with a reasonable assumption that no one is tampering with it enough to bury OS or firmware hacks. And if you're that paranoid, generic COTS might be an option. I might be missing something, though -- what is the use-case here?
Also, nail polish is a good low-tech solution but now I need to clean glittery stuff of my work laptop. The NSA can find nail polish, too.
Nevertheless, glad to see Purism is still going hard at it.
