This is a great product! I was exposed to Smalltalk in BYTE August 1981 magazine as a kid. I never had access to it until now. Worth the wait.
I have used dozens of computer languages, and earned a Masters in Computer Science with Software Engineering emphasis. In one hour, I was exploring Smalltalk and doing math at the command line. Next day, I used an hour exploring OpenGL with Smalltalk. This is a great language that is almost natural. I had to say thanks to all involved in making this software product. Now, I have source code from Open Smalltalk that I intend to use with Gnu Smalltalk. And I will attempt to share it later. — John
