I expected better, given Netflix and Amazon have been able to do it for quite some time with no problem. And I would still be willing to pay Disney's current price given their content selection if they were able to deliver it reliably on other devices, but I've been disappointed so far.
Disney are the single biggest contributor to the shitshow that is copyright law right now. I don't understand why anyone would expect them to play nice.
Personally I view is as a moral imperative to not give them any money.
