No I haven't, and I am somewhat curious, but I'm also keeping up with it through some of the swift/apple podcasts and YT channels I follow. For me it's more about the cost, physical overhead, and (apparent) lack of other utility, which all-together would to me be sort of a more involved commitment than some little thing I may or may not ever bring out..
I'd only ever consider bringing something that is nearly invisible to both myself and others in terms of weight and required infrastructure, wouldn't bring anything with me for the purpose of occupying my attention that I can't forget I have, or that would consume more than a negligible amount of space/weight; I'll bring a book, but not a tome
Incidentally, Canadian cross-country trains don't even have outlets at the seat as far as I know; they're quite old sadly.
That said, I buy almost no superfluous electronics for raw consumption, and even an iPad Pro would be wildly out of scope, as nice as they seem to be, since although they do have other utility, I can't picture myself doing more than reading or watching videos. On-the-go entertainment is something I try to keep at arms length so I can spend that time at peace.
Fwiw, I do also hope it doesn't become normalized, not to squash others' potential for fun, but because our existing devices already enable people to protect themselves from social interaction on a large scale, which strikes me as damaging.
