Well with the older models you absolutely didn't have to worry about things breaking. I used and abused a 13" late 2012 model for about 4 years: * Used it under direct sunlight (and I live in Singapore so it's both hot and humid) multiple times * Took it out to sea on boats multiple times for testing robotics * Dropped it on concrete accidentally * Left it in dusty labs etc It's display finally died after being splashed with rain water but the machine itself still boots to this day. Apple made them really well but I can't say the same about the newer models.
