NOT trying to convince you otherwise, but... At the end of the day these are a piece of technology meant to be used.
I used to have a lot of that same mentality, but am mostly recovered now. I used to stress the same way about cars as well, try to keep mileage low on my weekend "toys" etc.. Eventually I learned that all I was really doing is keeping it nice for the next guy.
That doesn't mean I want to be careless, but I do absolutely plan to where mine the same as I have with my previous "sport" models which means all day every day regardless of activities. I'm spending good money on it and I'm going to enjoy it without worry.
Same reason I moved to a leather sleeve instead of phone cases and screen protectors. And man do iPhones feel better naked.
Not suggesting anyone else should adopt my same mentality, but I've gotten far more enjoyment out of this mentality than I used to when I was overly protective of my "possessions".. At the end of the day, its all just stuff...
Battle scars (within reason) are all just part of life.
