I got the Google device, along with an Amazon one, to compare and contrast their utility. The only use I could find for the Google Home was as a radio. I gave the Amazon device away: I gather it spends its life in a cupboard.
I have a lot of radios - the DAB ones are terrible, the FM ones are either small and tinny or space-hungry. The one thing Google (and indeed Amazon) have got roughly right is producing a decent sound from a relatively small device.
