I have two (one bought, one gift) and I use them every day, albeit for a limited range of things. I think part of our disagreement may be that I’m not counting native functionality like Prime music streaming as a skill. Mostly, the core functionality is useful and well implemented. Though things like sports scores are still desperately limited, for no good reason. The only UK soccer it know about at all is the Premier League. If I want to find out who Oxford United are playing next, I have to ask OK Google. And good luck with less popular sports.
But, for instance, on recipes/cooking, I’d be interested to hear your experience. I don’t want something that just steps through a recipe, I want something I can interrogate on a random access basis (How much cream do I need? When do I put the chicken in?). None of the ones I’ve researched allow that sort of flexibility, and as a result aren’t any better for me than just having Pepperplate open on a tablet.
And, more generally, I wish Amazon would change their setup so skills in general, rather than a handful of curated ones, can respond to ordinary language questions, without having to do the whole “tell skill to x” rigamarole.
