Again I just want to correct you over one small detail.
People aren't getting upset, we're laughing at the ridiculousness of the situation. Sure, you can return anything to Apple for any reason as long as it's within whatever time period they specify, but it doesn't mean that the reason isn't ridiculously silly. I'd be red with embarrassment if I walked into the Apple store near me and told them I wanted to return this machine, not because it doesn't work well (and oh, it works well!), not because of the battery life (which is amazing btw), not because of the screen (which I was worried might bother me, coming from a 14 MBP, but it doesn't - the screen is great), or the keyboard (identical to the MBP 14, and a huge step up from the keyboards of a few years past), no... I need to return this because I saw a fingerprint on it, and that upset me, a grown adult.
I'm not asking how it is possible for people to return an amazing product for such an immature reason, I have eyes and ears and am well aware of the incredibly stupid times we're living in. I wouldn't even go so far as to say I care (as in this is something that's important to me, or that I'm passionate about). I'd say I'm laughing. I'm getting entertainment from this. The same way I would if I watched a stand up comedy special on Netflix, or any comedy at all really. It's making me laugh, and when I laugh, I feel good.
