Amazon is number 1 in online sales and number 1 in cloud computing. I am not sure who is number 1 in online assistants. Google has Google Assistant (Google Home?), Apple has Siri, and Amazon has Alexa.
Google has Google Music and Google Play for Movies. Amazon has Amazon Prime for Music and Movies. Apple has the infamous Apple Store for everything Apple.
It is starting to make sense to stay in your ecosystem when deciding on certain technologies.
I recently purchase Amazon's Fire TV Stick for the above reasons. I have a subscription to Amazon Prime for music and videos and the fact that the stick hooks into Bell Fibe (if you subscribe) was a bonus. The fact that the stick's remote has Alexa cooked into it was the overriding factor in the picture.
Alexa and the fire stick can even work with my Google calendar. I think it may be time to get a Amazon Dot to make full use of Alex, like setting an alarm for waking up in the morning.
The only downside to all this is that these companies know everything about you. These devices are always listening, but then again, I have nothing to hide :-)
