I suppose because I've seen my Apple Watch struggle with the most basic of things. Like displaying a text message, or scrolling through a full set of apps. It's never felt like a speedy device, and seeing something render so smoothly like this gave a contrast to how I usually feel. That help?
The first gen watch was very much like the first gen iPhone - a cool tech demo on underpowered hardware.
It was supported far too long, and with its final updates it was barely suitable as a timepiece. It couldn’t handle the most basic of tasks, like receiving messages or playing MP3s on your AirPods.
Could be, the date I mentioned is when I could afford buying a P166, and I didn't bother to check the interwebs for the release date, now I have gone and found it, depending on the exact variation from P5 or P6, it could have been released between 1995 and 1997.
