I don't live in the US either. But this website is primarily US-focused, and most people on it readily assume the context for everything is the US, so I conform to the same habit.

My anecdotal examples would be mostly middle-class families and college students in the US, not particularly valley-related. In my country these type of devices are on the market but not popular (only seen a couple), but they're priced out of the range of the majority of the population anyway.
