I currently use a Thinkpad T440s which fell down several times from all kind of heights and it looks mostly totally like new. At one drop down one bit of the steel was squeetched a bit at one corner but it dropped from 1.70 meter down on exactly that angle on the hard floor. The iPads I used were not that forgiving. How rugged is the new rMB and which military standard does it have for ruggedness (if any)? Is there hard case available from apple or any other known company that protects the notebook from drops?
