       | I don't think I ever thought much about that light but now after
       | reading this article...it really was a pretty cool and useful
       | detail.
       | 
       | The info about how the light's rhythm was meant to be similar to
       | human breathing is cool too.

       | I think all my laptops' LEDs first blink wildly when I close
       | them, then change to a slower rhythm, that's not an Apple
       | feature.

         | 
         | My desk was at the end of my bed. The MacBook with sleep light
         | was always on that. It was _never_ bright at night. Dimming
         | half a second after I turn the light off. Even if the lid was
         | closed.
         | 
         | Oh, also, you can swap batteries of Macs during sleep if it has
         | a removable battery, without losing state.
         | 
         | This is why Apple is Apple.

       | The dot in the "i" in "Thinkpad" on my laptop's lid does this,

         | Trackpoint's red color is also a story worth reading.

       | I think the sleep light on the white plastic iBook was the first

       | be so lucky as to invent a single thing as great over the course
       | of my lifetime.

       | In the Choose Your Own Adventure novel _Supercomputer_ , you
       | receive as the grand prize in a contest an AGI-capable computer
       | and go on various adventures with its advanced thinking
       | capabilities. One of its features is said to be a "smile light"
       | which illuminates in a pleasing greenish color when the machine
       | is happy. The breathing light always reminded me of Conrad's
       | "smile light" and just went to show that Apple engineers were
       | reading the right type of science fiction novel.

       | That light was a big deal - I remember when I got into Arduino
       | years ago this was one of the common projects people would do to
       | add a breathing LED to everything, including a pumpkin:

       | It could absolutely be false nostalgia since I was a Mac fan from

       | slick and performant but still serviceable.

       | Ironically, after a series of uninspiring Windows machines the
       | next laptop that made me feel any level of enthusiasm like that
       | Mac is my current Framework 13 running COSMIC on NixOS. Quite an

       | One of my early mentors worked on it. They mentioned the
       | pulsation for the sleep indicator was modeled not just on the
       | human respiratory rate, but specifically that of a _sleeping_
       | adult. It came up when we were playing around with on /off
       | dimming curves for a room based video conferencing product and
       | discussing physical analogies we could model a curve on. Fun
       | afternoon exploration, but in the end we just stuck with ease-
       | in/out. I miss when you didn't need to overly justify taking an
       | afternoon detour to explore whether something could be improved.
