(How) do you use Cortana in every day life?

Hey guys,

Since Cortana is not available in my region yet, I'm curious to know if she has proven useful in every day life, or if it's rather gimmicky at this point.

  • Do you use Cortana every day?
  • What Cortana features do you use most?
  • What features turned out to be disappointingly useless or impractical?
  • Does she actually seem like a personal assistant to you that helps you get through every day life more easily and efficiently, or is Cortana just a nice little feature that can do a few certain things?
