The short answer to the question - No.

Cameras are just tools, a means to an end. Expensive tools, so it's natural to take reasonable care of them if only to ensure continued reliability. But I really don't care about resale value, so the occasional ding, scuff-mark and user wear is par for the course...
Exactly.
As long as it performs like it's supposed to and the pics are fine, what is there to be concerned about.
As my camera tech once said to me when I was complaining about dust..."The only way to keep your gear pristine is to put it back in its box, wrap it in plastic and put it in a cupboard - and leave it there. It will always be perfect. Get out and use it for what it's designed for."
Since that day, I haven't worried about it.
