Memetic,
all use banned in flight just because some people can't or will not disable WiFi - especially as some airleins are just bringing in in flight internet access
You might just see it banned like cell phones were. They will want people using their equipment to access the net, just like the flight phones. (They charge more per minute for a phone call than the Printer Ink Cartridge Makers do per ounce of ink.)
Take Care,
Richard
