Damn that's harsh. They're still your family!
Why do you need a case for your laptop? I've never dropped a laptop in my life (I have tripped over cords before but the magsafe has saved me every time). Shit, I bought the very first iphone the day it came out and I haven't used a cased on any of my phones either and still have never broken anything despite dropping my phones every once in a while.
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.
