Isn't it weird to name it "ORIGINAL android demo" since that implies that the author new that in the future there would be other android demo.
It'd be like asking a solider in 1915 what war they were fighting and they respond "WW1" (as if they new in advance that there would be a second world-war 30 years later).
Since I wrote most of this doc in early 2020, it takes a look at the demo from a modern point of view.
In fact, when I was using the demo it felt like the color flip phone I used to have around the mid 2000s, and in retrospect it's hard to tell why Android became what it did today. There wasn't much unique "smartphone" functionality in that demo from today's perspective, although I didn't see the original materials about how it was positioned.
