Reading Speeder's recent blog post (which is here
), I suppose it would be important to bring some of the discussion here, as well as place some input myself.
I can agree with many of the points that have been made. Windows cannot possibly be equal to a PC. You cannot compare those two together. It's rather like comparing a bed to a room. There's nothing really to compare them properly upon.
Nearly every machine, be it the gaming console, mobile phone or even television, is a PC. It takes data, be it read or input, and outputs it into something that is useful for the user.
The way that the wording is done is quite important, yet many still get it wrong, including those Apple ads that seem to poke at the 'PC', when they're in fact referring to Windows. Maybe that's how they've gotten away with it...
