The only thing that looks interesting is the Echo Hub. But I don't trust Amazon to not screw it up by placing a bunch of crap that you can't get rid of on the screen like they do with all of the Echo Shows.
Your iPhone/iPad or Android phone/tablet gives you control over what is on the screen. You can put icons here, widgets there, and all without intrusive advertisements or any content that you didn't specifically put there yourself. What's wrong with Amazon? The Fire tablets, the Echo Shows, Fire TV stick, and basically anything that Amazon makes doesn't follow what Apple and Google has proven to work well on their devices. Apple/Google makes money by taking a cut from the apps users install. Their devices are free from content that the user did not put there themselves. Why can't Amazon do that?
Amazon is trying so desperately to monetize that they've essentially dug a hole that they can't ever get out of. Even the Ring alarm system. It used to be that you can turn on/off your alarm when you are away from home. If someone breaks in your house, you'd be notified on your phone remotely. You gotta subscribe in order to do that now. If you don't subscribe, you don't get the notificiations and you can't turn on/off your alarm. Isn't that the point of an alarm system?
So basically I've lost confidence in just about all Amazon-made devices. It doesn't matter how great or innovative their new devices are. Just the fact that it's branded Amazon (Ring, Blink, etc.) will make me and probably others think twice.
