I agree with your sentiment that this device is for people that want the hub features foremost, but I think that strategy is flawed. I would imagine most everyone that wants a hub device already owns a Nest Hub or Amazon Echo. And for the same reasons the Apple HomePod and Google Home Max failed (way too expensive) I think this will fail also. People don’t want expensive home devices.Tbf, I don't think you are the target market for what Google imagine this device for. Its targeted for those who are interested in a Google Nest Hub device first and foremost. If you are not interested in a Google Nest Hub... then, most likely you would label this whole 2-1 useless.
People use these devices to set timers in the kitchen and play music. I can’t figure out why they decided a $500 home device was what was missing in the already saturated market. Hope to be wrong because I always root for Google.
