quite interesting and handy IF they really do all know the rules
"The U.S. Transportation Security Administration announced Tuesday that fliers who bring an iPad through security will conveniently be able to leave their device in its carry-on bag, unlike with a traditional laptop.
According to The Associated Press, the government agency said that most who travel will not need to remove the iPad from their bag, because the device is relatively small and doesn't have "bulky" accessories such as external drives. Those accessories can make it difficult for X-ray scanners, who see a cluttered image when a laptop and all of its accessories go through the machine in a bag.
However, the TSA cautioned that fliers may still be asked to remove their iPad if the scanners cannot get a clear image of the device.
Spokesman Greg Soule told the AP that the TSA is in the process of telling its employees how to handle the iPad for screening procedures. With 300,000 sold on the first day alone, and a 10-hour battery life perfect for watching movies or playing games on the go, it's a device they'll likely run into on a somewhat regular basis."
