Skytrans Airlines up in Cairns now ask the passengers to surrender all hand luggage for this very reason. I doubt the 404 seats are indeed rated to 25Gs.
Funny enough, if a plane crashes, a bloke carrying a laptop would probably kill his fellow passenger but keep his hardrive intact as theyr'e rated 30Gs+

I don't recall the details but I think the Titan and similar era aircraft seats are stressed to 9G. Then the FAA changed the design rules and required new designed aircraft to be stressed to 25G. An example was the "new" Cessna 206 (with the Lycoming engine) which grew around 90 kg over the original Cessna 206 (with the Continental engine) due to the seats meeting the new design rules.
