[Lord Mahoney]

Devices with backlights/frontlights will always have physical differences from the devices without. It's been like that since the Game Boy Light. Sometimes it involves compromises like dust getting in, layers not being vacuum tight, and yes, added fragility.

You just have to weigh the benefits of having the light. Is it a necessity for you? If yes, just be a little more careful with your device, that's all.
