I can almost guarantee you that there will be a ban on using Laptops in Airplanes happening very soon. Some airlines have already banned the use of Dell and Apple computers in-flight. The latest laptop to blow up was a Thinkpad and I am sure if it had a Sony battery in it that it will be added to the list of banned devices used at 35,000 feet. [Engadget]
