Apple

So, you're a klutz who is prone to dropping your phone, and might want to sell your device later on, and still you're asking to go caseless? A case isn't just to protect against drops, but it's also helpful for grip as well. If you care at all about your device and actually plan on selling it, just use a case. If you didn't plan on selling it eventually, I don't see the problem but if that's your goal then your best interest is a case. Even if it's just a thin one.
