I have used Windows since the "beginning", but I have not seen Microsoft create anything innovative, not even Cortans . It took Apple on its death bed (with their poorly-selling computers at the time) to come up with iPod, iPhone and iPads to shake up things.
I have Cortana on my PC, but don't use it and nor do I want my PC running my home gadgets. I like portability so use mobile devices like iPads and iPhones with great apps installed and many inexpensive gadgets like Dots. I can use these gadgets from any room and turn on lights, and access my data from a centralized NAS home server. Meanwhile, the computers, although laptops, are connected to other gadgets like printers, drives etc, so they are less flexible to use since they are tied down with stuff.
Talking to gadgets to get things done is not all it cracks up to be, and maybe I don't want to speak all commands; I may want to silently "tap" on a screen instead. My vision has been failing, so I likely may be doing more talking and less tapping as time goes on.
It's nice to have all these various ways to interact with gadgets, and I choose what I like best for the task to perform.
