I guess everybody's different. I personally like the idea of being able to, say, ask what events I have on my calendar for the day while I'm getting dressed, and be able to get a summary and then engage in followup conversation about it. Or have a little reminder that says, it's time to leave in a few minutes, would you like to turn on your car's climate control? It's not to replace my normal computer usage with a voice interface, but to add new capabilities.
