I really want to see what Cortana can do.
Apple should not cripple this service; allow "Hey, Cortana!"
You may blast me for this, but I find Siri incredibly stupid and usually cannot answer my question, often not understanding it correctly.
Further, for dictation, Siri, or iOS, whichever is in charge of this, has no way to learn, thus it continually misspells my Kids' names and cannot spell them. I hope Cortana does better. Siri needs some serious competition.
