I initially hoped it would have a hub specific interface that looks similar to the Nest Hub. Instead though, the dock basically puts it into screensaver mode and the home icon pulls up the basic Google Home like if you were to tap the quick settings icon.
As a tablet, it's decent but I wouldn't get it if you're mostly planning to use it with Google Home as I think the current experience is disappointing.
I left and deleted my account after Elon changed the algorithm to show nothing but his posts. With this decision and the many other bad decisions he's made since buying Twitter, I'm glad I left and I frankly don't miss it.
This will absolutely be abused and people will be harassed, but I feel this is intentional as he continues turning Twitter into a far-right echo chamber.
