Re: A free Siri/Cortana/Alexa clone,
"It will fail because it's a gimicky toy,"
It depends on how it's used. I've been driving along and had to go to somewhere.
Phone Cortana from steering wheel controls
Cortana, navigate to XYZ.
Done.
No need to stop, no need to take hands off wheel, can happily concentrate on road.
I probably use Cortana more in the car than anywhere else. My kids use it in place of Google.
