I’ve got a Home and a Mini.
Whilst not essential, they’re bloody useful if you start using their intelligence. I always use a similar example to above – If I’m in the kitchen with food all over my hands, I can tell it to play whatever music or radio station I want. My son comes in asking if he can watch telly before dinner, I can get it to turn on the lounge TV and start playing Transformers on Netflix. I can then carry on cooking, get it to convert ‘cups’ of floor to actual real non made up units, then set a timer for the food I’ve just put in the oven. And then add any ingredients I’ve just used up to my shopping list.
If I’m in the garage working under the car with grease all over my hands, I can ask it to convert ftlbs to Nm, play a different song, then broadcast a message to the house that I’ll be finished in half an hour or so, so that my wife doesn’t think I’ve been crushed by a falling Saab.
That’s all with very little in the way of home automation, just Chromecast and Homes.
They’re not perfect, but they make some parts of life a little simpler.
