Well just to post a few more info, now that I've had my case quite a while...
I currently have the Seidio Active Limited Edition - Black case on my Evo
1) The silicon parts do not come off as some have suggested, however I never place the phone in my jeans pocket. Only when wearing dress pants so perhaps it's the 'tightness' that causes people to have that effect?
2) Protection - I can't speak to much about dropping , as I've only dropped the phone once, luckily on carpet. No ill effects but probably would have been safe without the case in that instance. It HAS saved my phone from any and all scratches from sliding it across the desk, fast food restaurants etc..
3) Cleaning.. About once every other week, I remove the entire case, run it under warm soapy water and dry it. Just to get rid of the fingerprints/oil that build up. Occasionally I'll wipe the back with glass cleaner, after I'm done cleaning the screen

The phone looks brand new when outside the case, not a single scratch on it. (Of course it's only 90 days old.. but still).
4) Camera lens has no scratches that I can see , and I'm always putting it screen up so it holds up pretty well and just enough off the desk that I feel I'll never have an issue.
My only complaint has been the power button. Even after 3 months it's not broken in enough to use without my home made 'mod'. (I cut a tiny square from a business card, the same size as the indent above the power button, and place it inside to give the button a bit more leverage. Occasionally I forget about it when cleaning the phone and it's very easily missed when trying to turn on/off the phone.
I was a bit saddened to hear the Sage color on Amazon was not as bright as the picture (I love that neon green look), and was about to purchase a Burgundy one when I noticed there are TWO new colors on amazon today, all in stock!
So that brings the Active Limited edition cases to:
Sapphire Blue
Burgundy
Sage Green (Olive dark color, better representation on the picture on the holster combo )
Black
and now...
Pearl White (

Amethyst (

I think I'll pick up a white one, hopefully it doesn't get too 'dirty' over time.
