I took mine in a backpack up to my parents place and apparently something lightly caused a scratch on the screen so now I just have a permanent little gouge.
Thankfully I've learned to ignore it over time but yeah, don't assume it's as indestructible as a lot of screens.
The DC-1 does/did ship with a padded cover which makes me think it doubled as the engineering fix for when/if they realised that might be an issue.
