Charlton Heston said it on a TV newscast using gun instead of laptop. some people feel the same way about their puters. Check out You Tube for his statement Re: Gun Control
OR....when the Lithium batteries catch fire on your lap. There have been several recalls over these batteries, and just this evening one of the news channels showed a video of a couple of young guys sitting at home with a laptop charging on the couch. It caught fire, but they had the good sense to hurry up and carry it outdoors, where it flamed up 2 or 3 more times. Had it been charging unattended, it might have caught their house on fire.
