The Smalltalk-78 Xerox NoteTaker in-browser emulator has drawn interest for its unique programming environment, reminiscent of early computing. Users appreciate the interactive and graphical nature of Smalltalk, which contrasts with traditional UNIX philosophies. Some users enjoy experimenting with Cuis, a current version of Smalltalk, while noting that Smalltalk's complexity and openness may have hindered its widespread adoption compared to more closed systems like Apple's. The emulator enables on-the-fly modifications and curiosity among hackers but raises questions about downloading for offline use and the implications of shared JavaScript changes. This disparity between the open-source nature of Smalltalk and the success of closed systems highlights ongoing debates about innovation versus accessibility in technology.
