The CM-5 LEDs had different settings options: on, disabled, and also a “random and pleasing” setting.
So in one respect, modern RGB LED motherboards utilize trickle-down supercomputer technology in the form of... blinkenlights.
Underrated comment; Pages is a page-layout program. I've used Pages '09 for professional work (system architecture, audits, etc.) and it could do things that Word simply could not. Capabilities-wise, it felt closer to InDesign.
Then in the next version, Apple dumbed it all down with the "panel"-style UI so it had similar UX to the iOS and web versions. It lost features. It got many of them back over the years, but that design move really broke my workflow for a while. I just kept Pages '09 around until the new version had parity, more or less.
It really does work well. I got used to my Office-using colleagues asking, "how'd you do that?!" Downside is you are in a bubble and cannot round-trip documents without losing the really good layout stuff.
