(translated from sebsauvage)

To the people who says that Linux is good to do handycraft but it is not as professionnal as Windows or Apple : in the big league - the real one of the TOP 500 - 100% are running Linux.

Ah and your box ADSL runs with Linux
and your TV
and your smartwatch
and your smartphone
and your digital pad
and your ChromeCast.
and your reader
and your Internet Service Provider
and - except if you have an XBox - your games console too.
Google, Facebook, Twitter, Amazon, Flickr, Netflix... they are all running Linux.
Even Microsoft, in his big cloud "Azure", sell more Linux instances than Windows.

So in bulk, everyone runs Linux or similar such as BSD.
It's only your little PC that runs under Windows. With its preinstalled "Candy Crush".

Donc en gros, tout le monde tourne sous Linux ou ses cousins comme BSD.
Y'a que ton petit PC qui tourne sous Windows. Avec son "Candy Crush" préinstallé.
