I know of Pharo (have used it a little bit) as well as Dolphin, Squeak, and VisualWorks. I've only talked to someone who has actually made money from a Smalltalk app once before, although I'm sure it's not that rare. I'd like a little more information on how efficient they are...etc besides just seeing a few success stories. Thanks for the help though, always nice!
For the past 10+ years I was working professionally on a Visual Smalltalk application, maintaining and enhancing it over time.
Visual Smalltalk is no longer commercially available but in terms of memory requirements it was highly efficient because it was designed to run on PCs of 20 years ago.
