Results have come in from the latest IDC survey which asked travelers their opinion of cell phone use on airplanes, the survey found that only 11% of 50,000 participants said they would use a mobile phone for voice calls when in-flight. 64% approved of using their mobile phones for other activities such as text messaging, this was their first choice.
An airplane with half of its passengers making voice calls would be a nightmare, an airplane with almost everyone tapping away on their Blackberry would mean a nice quiet time to catch up on Zs.
Aside from mobile phone use, I would rather see a greater effort to bring WiFi Internet to airplanes; this is happening more over seas and is costing upwards to $30 per trip. United Airlines recently announced their efforts to bring WiFi in-flight, it may be some time before we can actually see it in action.
