setting alarms in the morning without having to wake myself all the way up with that bright screen is the best. While it's plugged in, I can wake it up using just my voice.

In the car, I use it to open my music player, I just wish I could tell it to play too. I set reminders and calendar all the time, so I basically never forget stuff anymore.

Also weather, sports scores, looking up facts while talking to someone (so I don't have to get out of the convo and stare at the screen).
