Your contention is that there are no Android or Android compatible smart watches or tablets? Are you serious?
“Viable” Alternatives, I think is what he is suggesting
Apple Watch is kinda the smart watch king in a product type that still isnt perfected, even flawed and being hyped up product that didnt change the game its just a nice accessory and periodically useful and Apple did better than competition (I have and like and wear often my S0, just saying it still has a ways to go)
And iPad is definitely the de-facto tablet king, more importantly. Lots of android fans are still glued to their iPads
