The John Sculley era of Apple has received a lot of criticism. With that being said, one of the aspects of this era that I'm most impressed with is the work that came out of Apple's Advanced Technology Group. During this time period Apple was serious about advancing the state of research in the areas of programming languages, systems software, and human-computer interaction. There were many great people that were part of this group, including Larry Tesler and Don Norman. I completely understand why Steve Jobs shut down this group in 1997; times were rough for Apple, and the company couldn't afford to do research when its core business was in dire straits. But I wish Apple revived this group when its fortunes changed, and I also wish Apple still had the focus on usability and improving the personal computing experience that it had in the 1980s and 1990s.
