Te lo dice Guy Kawasaki ! Lui ci fa “ben” 36 ore in stand-by.. Senza telefonare pero’ !
One thing to notice: I don’t talk much on the phone–“talk is not cheap” in my book. I am totally an email/tweet centric person. This clearly contributes to my standby time. I consider my iPhone a “tinytop computer that can also send and receive phone calls” as opposed to a phone that can “do email and browse.”
