Personal anecdote: I got one free at AWS re:Invent. I use it to play music of my choice (specific songs or playlist categories, which requires a subscription after trial period), set timers ("alexa set timer for 45 minutes"; "alexa how much time is left on the timer?"), do various calculations ("alexa what is 1 plus 1?" -> "1 plus 1 is two, but you already knew that"), and ask what time a nearby business closes ("alexa when does Target close?" yields the closing time of the nearest target based in the location I have set. If it's closed, it says when it opens next). Other than that, it's mostly just a novelty that I forget about 99% of the time.
