Comment: I would say refs http://www.theregister.co.uk/2012/09/05/qubes_secure_os_released/ and http://www.economist.com/blogs/babbage/2014/03/computer-security show enough notability for , in addition to sources from Theorem41. The article could probably use more third-party sources, though
Stance: keep
