In the fire situation, I'd go for my phone, but since thats an apple product has to be left out, so after that...
1. Car Keys, obviously my car is outside, but I'd want to move it away from the fire!
2. External Drive, since its got all my pictures music everything, and its the only backup I've got. (But my macbook would have been number one on this list, so I'd have most of my stuff)
3. Box of old nick-nacks. Over the years I've sort of collected things that mean a lot to me in a little box under my bed, so that would have to be rescued.
4. Other ornaments and gifts that mean a lot to me that wouldnt fit in my box would also have to be saved.
5. After that it would have to be my Metal Gear collection of games; just missing the original MSX version. I've got to admit I'm a huge fan.
It was quite hard to get to 5 though, but they're all things that are irreplaceable to me. All my apple things would be first out of the door though in a real life situation!
