I think one of the biggest reasons that iPads have been so successful is the accessory market. They are usually high quality. Accessories for Android tablets have always been “universal” and universally crap quality. If Google can get some high quality keyboards and cases it will help draw buyers. And things like the Square kiosk.
The iOS/Apple ecosystem is pretty tight too. I wish the Google ecosystem was better. I never know if it is worth committing when they might kill off an app/site.
I got the Lenovo smart screen when it came out and found it to be sub-par. I already have Amazon music, so don’t want Google music or YouTube music. If they had a better package deal for music movies and books, then maybe. Never bothered with the Google Hub for that reason. I got the small speaker for free and found it useless.
All that said, I love the Nexus and Pixel phones I’ve had, love the Pixel Buds, and recently got a Pixel watch. So the tablet is a solid maybe. Especially after how quickly the Nexus 7 tablet became bogged down.
