I don't know, do these small-storage-size models actually have that big a market share compared to the others?

They also sell 1 TB iPhones and I think on the latest generation the minimum storage has been increased. If nobody bought them they wouldn't sell them (see the lack of newer "mini" models).

I always thought that these models with tiny storage and tiny ram (for laptops) where just so that they could hook you with a low "starting from" price.

My point wasn't that "nobody falls into apple's trap", I'm sure plenty do. Rather, unless you're sure your audience is representative of the "wider consumer market", just asking them if they pay for icloud and they say yes, it doesn't prove much.
