How much abuse is it expected to take while in that rugged case? How much abuse does the iPad Mini get?
Saying "motorcycle" by itself doesn't tell me a lot. There's a difference between cruising down highways and motocross, staying in motels versus sleeping under a poncho in a rainstorm.
It's true that Apple doesn't sell ruggedized computers intended for combat forces and construction sites, but some of the very things that people complain about here - soldered CPUs, SSDs, and RAM - are "ruggedizing" practices.
As to taking "abuse," what does that mean? There are people who give their stuff hard use while commuting or in the classroom, while those next to them pamper their equipment. That's part of the fallacy of ruggedized gear - it can be an excuse for hard use.
I've been taking non-ruggedized cameras and recording/broadcast gear into the field for about 50 years - week-long backpacks, whitewater river trips, parades, rallies, outdoor music festivals, sports venues, theaters, concert halls, bars, thrill rides, piers, tour buses and seaplanes... A garden-variety protective case (nothing exotic) is all I've ever needed. I use my equipment with a reasonable amount of care wherever I use it - the consequences of dropping a microphone or lens on the hard floor of a studio is little different than dropping it somewhere outdoors.
