Looks interesting, going to have to keep an eye on that.
I think it is hard to compete with Photoshop because it is such a kitchen sink.
There is that, but I think it's simpler in scope, and harder to beat: They are the known name in the field. Just like "you can't go wrong with Microsoft" was the mantra for a while, "you're not a real artist if you're not using Photoshop" is a real thing.
yeah, the Creative Suite is a bit like Office too. Plus Photoshop has all the fancy plugins etc etc. But who really needs all that, especially now: I suspect people that might have bought before think would twice about a subscription. Or they subscribe and realise they're not using it enough to justify the cost and cancel.
I guess it's partly because it's got the kitchen sink that's it's such a snail. But then I think that speed was never particularly important for Adobe. When I first started using vector programmes, Illustrator 8 was a snail in comparison to Freehand 9. I eventually bought ai CS4 and it was slower again.
Earlier versions of Photoshop were quite fast though. (I dont have experience with anything more recent than Photoshop CS2. For fine-tuning photographs I was happily using Photoshop 5.5 for over ten years -- combined with a select edges plugin, it was all I needed.)
I think there could be a very big market for almost-as-good-as-Photoshop
(I see Sagelight appears to be dead.)
