1. You can buy 2-3 Echo dots for the same price. 5 right now if you go with the previous gen.
2. Alexa has supported this for years.
3. Much, much more smart products support Alexa than Homekit, and cost generally half as much.
4. Yeah Alexa has also supported this for two years now.
5. Why do I need this? It's a cute gimmick but other than that I can continue playback on my Alexa devices with a voice command.
So let's see: close to whole home coverage for the price of one Homepod Mini thanks to the Best Buy sale going on right now, the same if not better functionality in regards to communication and control of smart devices around the home, easy stereo pairing that improves sound quality dramatically with minimal effort and supports ALL music streaming services including Apple's? Sorry, but no. Apple needs to try a lot harder and compromise on their ridiculous price margins a bit more before I'd ever consider abandoning my Echos for HomePods, Mini or otherwise.
