Exactly! That's what I am talking about. There is no such thing as an objective measure of the quality of an OS, whatever billranton wants to believe. Whatever measure you come up with will always be subjective.

For some people here, an OS is a means to an end. The most of the world does not give a crap. An OS is a tool, and a very low level one at that. You don't care who supplied the screws holding your kitchen table together, as long as it fulfils its function, holding your plates so you can have your dinner on it (or whatever you do on your kitchen table). In the same way, no one cares what OS runs on their phones, as long as they fulfil their function, making calls and sending SMS, emails and Whatsit messages.
