Original Smalltalk was always "full screen" so it is strange to argue this way. Anyway, there are still Dolphin Smalltalk and Smallltalk/X (jv-branch) under active development that use OS windows manager. Pharo will allow working this way soon as well. On the other hand, it has own downsides if you work in multiple images at once and mix their windows together.
