Yes if it's 100% reliable and I'm alone then I'd have a low treshold. But it feels weird having a UX that works when I'm alone and isn't accessible when I'm not. On your phone you can just enter "eggs" to your shopping list. But if devices move away from the general purpose input UX, then you'd have to talk to it on the bus. And when it's only 90% reliable you'd have people shouting shopping lists on buses...
