So, let's take Pixelmator as an example. They easily bought me with their promise of a streamlined design and simple to use tools. Their demos looked so cool, that I've easily paid $40 (I think it was $40). Then, when I started using it, I realized it's missing some super-simple features (that people request on their forum) + it's not so stable, it freezes and crashes sometimes. (Also, can't remember the exact features that I was missing) So, now, even though I have a paid for Pixelmator, I still have to ask my wife to do simple edits in her Photoshop occasionally, which I hate using.
So, what I'm saying is that selling to me was not a problem at all, if only they could deliver a good product. I also used Sketch as an example of a product that works great: it's cheap, it probably misses tons of Corel Draw features, but it's simple, cheap, and perfectly serves needs of those, dealing with web/mobile design.
So, should there be a similar product for raster graphics and video?
Also, NI on the audio production market feels to me as up for disruption.
