Its a flimsy thing anyway, feels very brittle.
So have you already broken it off / pulled it off to leave your USB port exposed 24/7 ?
EDIT: [post #15]:
Thanks for responses thus far. Drivers behind the question were:
1] Is there any adverse effect of having the port exposed 24/7 ? If not, why have a cover to begin with...
2] Many stateside Pre owners reported issues of the case or screen CRACKING when popping the USB cover back in ==> want to avoid!
