I've checked out the two BB10 Blackberry devices at various cellphone kiosks - the first two times I got lost not knowing the gestures, the 3rd time I knew from reading online. After three kiosks, I still have never seen the tutorial. Obviously I would see it if I bought one, but first I need to decide to buy one.

That can't be good for BB.

I meant it's discoverable in Jolla. They offer a tutorial. There should be a way to view it again probably, in case you aren't using a completely new installation.

BB10 has a similar tutorial. As I said, it's never turned on in store demo units.
