I know three people with them, two of them now have them sitting in a box somewhere the other one said he doesn’t use it for anything other than the weather or time but is now seriously concerned about it’s privacy implications so is considering unplugging it. Personally I use Siri on my phone probably more than 20 times a day on average and find it very useful, it helps me set reminders, events, send quick messages etc... without the full cost of mental context shifting.
