You should check out a Smalltalk environment that isn't Gnu Smalltalk or Redline Smalltalk, neither of which currently has the full Smalltalk IDE experience.

"Pharo By Example" would be a good starting point. If you are interested, feel free to email me, I'm quite happy to introduce people to what a Smalltalk environment has to offer so they can take it back to their day to day and start to spread the ideas.
