well it’s a six inch display so presumably it’ll be a lot cheaper. maybe designed with an always-on display. And the UI optimized for home oriented stuff. could be interesting.
I'd rather have properly working accessories that connect using Thread (not Wi-Fi) to one another and work without requiring a separate app. Currently almost every manufacturer requires their own proprietary bridge or they want to connect directly to Wi-Fi.
Give me a button/switch, climate sensors (Eve Room comes to mind as it has Thread but it's a PitA in some other ways), thermostats that can adjust based on an external climate sensor, lightbulbs etc.
Apple TVs and HomePods already work fine as a "Home hub", I don't need a separate, central display.
Unless priced extremely cheap, or Apple plays the walled garden game with peripherals and/or restricts current device capabilities, it is unclear what this device offers more than what iPad or iPhone already does for managing home devices.
