• Separate batteries. Using a device for music and a standard phone drains from the same battery. You could carry a power brick, but then you’re carrying two bricks for worse audio.
• No camera. Certain work assignments won’t allow me to bring a device with a camera into those zones. Or, if I do, the transition process is so intrusive that it’s not worth it.

Those are the only unique characteristics. You can compensate other differences on a phone like adding an additional DAC and/or amp.

I own this.

I’m guessing the author doesn’t have this issue, but the model sold in the US has a volume ~~limiter~~ limit on them. My daily headphones aren’t easy to drive, so this was a concern I have that many other people might not care about.

I ended up having to import mine to get a device that doesn’t have this enforced.

Edit: Sorry I was clumsy with my words. It’s a limit on volume, since it’s an option for high gain.

I would have expected studios to use a 3rd party system back then. GameSpy was huge in that era to cover that functionality.

I use the Ecowitt moisture sensors for potted plants. Given their size, I wouldn’t recommend using them for your lawn because you have to be sure to not hit them when mowing.

Automated irrigation systems are reasonably consistent. I moved from my lawnless apartment to a house with a backyard of grass. I left out a few empty containers across the lawn, waited for the first watering cycle, and adjusted the timings based on the distribution.
