I have a surface Laptop 3 and a Surface Laptop 5 I purchased only 2 weeks ago. When the Surface 3 cracked, I assumed it was something I did. Then a crack appeared on the Surface Laptop 5, running from middle of the screen to the top camera - I haven't even taken the laptop off my desk yet.
These are hairline cracks, only visible at an angle, but still annoying and is clearly a design flaw.
