You were lucky then. On both flights to and from Vegas, we were specifically told that if an electronic device has an on/off switch it must be turned off until 10 minutes after take off. We even had to turn are cell phones completely off, no Airplane Mode, and the flight attendants were fairly militant about it. And let me tell you, the majority of passengers on both flights were attendees to the CES so it seemed a little ironic that we had to shut down our technology.
