Cortana is too many syllables. I hold the search button if I'm going to talk. If my device could utilize Hey Cortana, hands free, I'd use that feature. I've always felt weird talking to a phone without a person on the other end but that can change if doing so can make life more efficient. Still waiting for the next 920 upgrade in 5"ish size, then it's Hey babe, I mean Cortana.
