Wow. I have to say... you're a FOOL! Maybe you need your eyes checked. I usually try not to get rude on forums, but what kind of moron even lets a thought like that make it past his gums?? A cracked, scratched camera lense doesn't affect the picture quality?? Wow.
I have the EVO. I've had it for a year now. Some stuff I've learned...
1. There is NO RIDGE! The phone most certainly DOES sit DIRECTLY on the camera FACE! Yes, it's at an angle, and it mostly scratches in a crescent shape around the bottom first, but it eventually spreads like cancer across the lense because not everywhere you set the phone is a perfect surface.
2. What we're talking about is the lense COVER, thankfully. Not the ACTUAL camera lense. It can be replaced, and is really cheap and fairly easy with a pair of tweezers.
3. It's NOT gorilla glass. It's not even glass. It's plastic. I can't IMAGINE what you'd have to do to crack it, but it does scratch EASILY.
4. When it's dirty, or scuffed. Your pictures will suffer GREATLY. Not only can the light not make proper pictures, but the camera wont be able to focus as precisely either.
If you doubt me, put a soda can on your desk. Take the best picture you can get outta your camera. Then remove the battery cover. Pop off the red bezel. (it's only on with double sided tape, and it'll go back the first couple times, dont worry) Then pop off the little cover that says "8 Megapixel" to expose the camera underneath. Now repeat the picture. You're gonna need to change your drawers when you see the difference. Case closed.
