I’d say it’s actually been power-user friendly 3 times:

1. The Apple II

2. Late 80s/early 90s when screen savers and [I can’t remember the name. Something makes me want to say ‘shell extensions’? small apps that made deep and wondrous tweaks to the system] were allowed to experiment with almost complete freedom

3. OSX. The first version was specifically designed for power users who had existing Unix/Linux skills. Special shout-out to some of the early tools as well: Automator, Quartz Composer, Audio Unit Lab, and even Applescript.
