You're probably thinking of Smalltalk as just another 'application' or 'language'.
Smalltalk is its own operating system, with an intrinsic (object-oriented) language, and Smalltalk-specific applications. It's an alternative computing universe, and only runs in a VM because there's no native hardware, unlike with Unix/C.
There's so little competition with software because there are relatively few coders developing for Smalltalk. There's been some effort to develop a Git client; with more developers on board, who knows what else might be possible?
At the same time, it would be wrong to shoehorn software on this system into paradigms that work well in mainstream OSs. For instance, there's no real need for an editor with the comprehensive feature-set of Vim or Emacs, because ST code is not developed in that way!
