Instead of "Second, Smalltalk is also a programming environment or IDE", I would say "Second, Smalltalk is also a live programming environment with it's own integrated and extensible IDE".

Instead of "With the integrated debugger, you are endowed with great power to prototype your application." ��I would say "The integrated debugger is exceptionally powerful.�� Not only can you inspect the execution state, edit and continue, you can also define new classes and methods, in the context of a live application you are developing.�� You can actually program in the debugger.�� Start by defining just a test and continue from there."

Instead of just "Class browser, code editor, object inspector, debugger, and workspace are an integrated whole.".�� I would add "All these tools, even the compiler and the class��system��itself, are implemented in Smalltalk.�� You can extend the tools to fit the way that you work, and because the system is live, you can do so while you're��programming.�� It really is the ultimate tailorable programing system."
