Let me just applaud the airline companies' for the noble lie that cellular phones will crash planes. A world in which every passenger on my six-hour, cross-country flight decides they're bored and this would be an excellent time to catch up with their awesome college roommate Dookie who's doing SO WELL and it's unbelievable that he has kids and does he remember that time when they...well, it's possible, under those circumstances, that I'd have to leap out the airlock. Worse, phone usage has a sort of epidemic quality to it, particularly in small, confined spaces. Since one nearby person on a phone means you can't sleep, may as well whip out the LG and call someone yourself. And since now the person behind you can't sleep, well they may as well see how Laura's doing. Etc, etc.
I am, however, totally stoked for airplane wi-fi.
