Adobe software is just too powerful to be replaced. It's like Autodesk. You can do almost everything there. This flexibility (and still competing with/being the most powerful tool in that niche) makes it almost impossible to defeat. Of course adobe is not perfect (very far from that) but their software is being developed for several years, is not something a startup makes in some months. Of course is possible, look at the example of Sketchup, there was dozens of great 3d modeling tools and they gained a good market position innovating where others grasp: usability for newbies. But they had to be great on this, good usability wouldn´t be enough..
