Seriously though, I often carry my laptop in a sachle bag. It doesn't have a dedicated laptop pocket, and often I like to ram it full of stuff. If I didn't my devices would end up scratched easily, and probably full of dust from whatever is lurking at the bottom of my bag.
Anyway... I always buy a case now.
My phone, however, gets dropped somewhat frequently, since by the nature of its use, it's exposed to much rougher handling than my laptop (which generally stays at home, or in my padded laptop backpack if I'm traveling). So I have an Otterbox Defender on that, which I'm sure has saved those phones many times. I would never go caseless on a phone; that just seems like signaling "I'm so rich, I can afford to be reckless with a $1000 phone".
