I love the look of the naked iPhone 4, but it is way too slippery for me. This is why I love Apple's bumper. Just enough coverage to give it a bit of grip and to keep the back elevated off the desk. The only thing I hate about the bumper is the tiny cutout for the dock connector. Apple sure loves dropping support for previous generations. My Apple A/V cable won't even fit. I had to take my rotary tool to the cutout and enlarge it. Now it fits the old style plugs, but it also led to an early demise of the bumper since it weakened it. It's just barely limping along for now since I can't decide if I want to get the new iPhone when it is released or just keep this one for another year.
Oh, and no need to for screen protectors for me. I never have and never will have on on my phone.
Sorry. A bit off topic. Naked FTW!!
