The "build quality" means it looks nice, but it sure isn't durable. If you spill liquid on an Apple, it's a dead machine. If you drop an Apple, it's also dead. Thinkpads can survive a hell of a lot more abuse.
Then I ask them to try the same with their Apple laptop.
That normally makes them never ask such questions again.
I learned that from an IBM (and later a Lenovo) sales person when presenting the X series. It's designed and built to tolerate real use. And some abuse :-)
I've used laptops for the last 10-15 years, often 8+ hours a day. I have not once dropped a laptop during those years. I'm completely okay with having a laptop that disintegrates when dropped and is better in other ways (thinner, lighter, longer battery life) as a result of not focusing on resistance to drops.
