I stopped by my local apple store and checked out the HomePod, while I didn't walk away with one, I was impressed with it. I also noted that Siri was less capable then Alexia, even among the simplest stuff. For instance, my kids like to say to alexia, sound like a cat, and it does (this causes massive confussions and consternation to our cats), and of course Siri could not do that. I'm not picking on Siri for such a silly request, but I point out that it shows the level of superiority Alexia has, that it indeed can do silly stuff, but it can do other things, like call an uber, or run multiple timers (Siri can only do one it seems).
Still even with the limitations, I'm likeing the HomePod and I'm leaning closer and closer to buying it. The question I have, is where to put it. I'm in my home office about 80 percent of the time, My bedroom watching TV/using my PS4, and the rest in the kitchen or living room. The natural answer is my home office.
