When ZBrush runs as well in Linux as it does in windows then I might switch, but until then I'm stuck with windows. And aside from some random code savvies getting it mostly working but crippled in linux, there has been no official release or even suggestion that it will ever happen from Pixologic. And I don't 3D without zbrush. As for Adobe, there are plenty of alternatives for each of their titles, so I don't see how anyone could say they're a monopoly. Far from it. They just happen to be an industry standard. Im not comfortable with their buyout of Allegorithmic but not much anyone can do about that, except buy a full license to substance while its still available. I've been looking at Corel's Painter recently and like it but I don't have $500 to drop on it or the time to learn it at the moment so I'll stick to photoshop for now.
