Apple

I can see it in some cases, but I've been warned away from using any case, even the ones Apple partners with and sells direct through their shops... I need something, my m3 will be traveling quite a bit, but I also want the system to last several years. I understand that the case needs to come off from time to time to prevent debris from getting tapped under the protective layer, that's fine. I'm not looking to protect it from drops so much as scratches and general environmental contact - would drand skin be better?
