The further significant slippage to seeing Affinity Publisher, even as beta, is a big disappointment and the first negative aspect I have had to say about Serif Affinity.
From the start, for me, Designer was always the most needed application of the trio to breakaway from Adobe. But OK, Serif's Affinity roadmap doesn't have to be aligned to me. So until now I have been interested and so far pleased to support Affinity with buying Photo and Designer for occasional use and to start to master it. But I remain totally dependent on Adobe InDesign - and will now be for at least another year... This is far from the roadmap and claims being given by Serif Affinity at the start.
I am sure it will be disputed that it is different resources, but it seems that the new Serif Affinity roadmap focusses on PC compatibility (which I believe is a positive for the longterm future of the products) rather than the original Mac user focus which was played heavily on at launch.
