Why is this at -2? It's a perfectly factual, if unprofound, remark on the linked article. I thought the same thing when I read it. Why identify Linux as a "desktop" thing? It's a unix clone, and remains so whether it runs on TVs or phones or telco racks.
Scratch that. I just realized that he wasn't referring to desktop computers when he said consumer devices. I now think he meant set-top boxes and things of that nature.
Of course there are plenty of desktop Linux distros, but most Linux machines in the wild are running servers.
