Re: "Surely true black can be rendered in RGB, with a value of 0,0,0?"
Also, a good few years back MS decided that for home users Publisher wasn't to be included in the Office bundle. Why, God alone knows. I'm not sure Microsoft did. I equate this with the point where they stopped taking any notice of what customers would want. But for SoHo users not having Publisher meant using Word instead. And also there was a host of budget DTP offerings that could be used to create a church or club flier, or a quick poster, or a birthday card and so on. And of course the home users who then found themselves needing to knock out a bit of quick DTP when they were at work didn't go to Publisher, if they were used to using Word. I wouldn't be surprised if many of them even got their employers to buy Serif's offering even though they had Publisher already.
