Microsoft has their own version of the Amazon "Echo" they look very similar, and last week I saw it at the Microsoft Store. It came out in Dec and it was on sale for half price ($99) this past week. I was told they have integrated Cortana with Alexa, but since I could have cared less, I didn't ask how. I don't even remember the name of their Echo knock-off.
I use Windows OS, but as for how the rest of Microsoft gadgets go, they ALL have been failures except for the XBOX. It's disappointing they are so incapable at innovation anymore; and I live in the heart of Microsoft and Amazon country.
