Lots more reasons why you might loose a laptop while traveling, it's not a dedicated plan for plane crashes.

Nope.

> Plan for a plane crash but not willing to use proper waterproof storage?

Yep. A ziploc bag costs me about a nickel, takes me five seconds to acquire (because I have them in stock), and fits neatly into my pocket, which is a really important feature for this use case. I don't know of any "proper waterproof storage" with those features. It's possible I'm being foolish, but I'm not trolling.
