Dell Store link to have linux preinstalled
This is not a real news (at least, if you haven’t lived under a stone for some months): Dell offers its customers to have Linux pre-installed on its “Precision” desktops.
You could also buy the FreeDos version, that is just like buying an empty, clean desktop or notebook and have the freedom to install everything you want, without wasting money in useless software such as… uhhh… Windows… :)
