Conclusion
If protection from damage and the elements is your main priority when it comes to a laptop case, then look no further than the OtterBox 7030. While the selection of colors is limited (black only) and the case is a little heavy, there's no better option for protecting your laptop from damage. Short of jumping in a pool or going down with the Titanic, the OtterBox 7030 will protect your laptop from shock damage, dust, and the basic elements - for fire elementals roll a saving throw (d20) at -4 versus fire damage.
