I've had a Framework 13 for coming up on 5 years now, and I've only had to replace the screen once: I over stuffed a laptop bag with 3 laptops through a cross country flight and when I pulled it back out the screen was dead. That was after about 2 years of daily use. I got a laptop sleeve to protect the laptop and haven't had any issues since.
I am thinking about getting the CNC lid, though, just to make it a little more robust.
