Hi greenboy,
Congrats on you new K10D. It's surely a nice camera.
You'll be surprised how durable Pentax camera is.
I got my K100D 2 years ago. And at that time I was also so protective too and babying it like you.
I put screen protection on back and top LCD until everything started to come off and look ugly.
So I decided to just peel it off and surprisingly that LCD withstand so much more abuse (not that I'm abusing it) than I thought it would.
Now I have K20D and feel it's so much more durable then my old K100D. Anyway K10D/ K20D are weather sealed and using more metal than K100D.
I'm sure your K10D will withstand normal abuse.
Maybe I'll just put an LCD screen on the back since my face's skin oil keep leaving mark on the screen :P
I noticed that the back LCD is more prone to skin oil. I don't see that much skin oil when an LCD screen was on it.
Just decide what you want your camera is for: Collector Item vs Excellent Photographer Tool.
then you'll know what kind of protection you'll need.
Don't forget to have fun.
