How do you protect a laptop from rain etc? I brought a Macbook Air 11" and on two occasions it stopped working because of rainy weather. Apparantly it's very sensitive for humidity levels. The battery shortcircuited and then it took three weeks before it dried up and functioned as normal again. I actually had a protective water tight bag, but it was too thin and it broke.. So packing electronics to be 100% safe isn't obvious.

I've never had an issue, and I've been dragging around a laptop for four or five years. Up until last year I'd just toss it in a protective sleeve (Booq Vyper), which woulda it at the bottom of my tailbag. Been rained on many times, to the point that the sleeve has gotten damp, but it's always been dry on the inside.
