Well I'm not a case person when it comes to sliders as I think they're just too bulky. Seems like the clips on the newest generation of them really don't interfere with the slider mechanism from what I've seen. So I saw this ultra thin case on ebay (think those snap on ones for the evo like the casemate barely there), and decided to give it a shot. I'm impressed. Looking at the Seidio pics, it definitely seems thinner and is very open on the face. The only thing it doesn't do is build up around the camera. Fit is tight. Clips are very non-obtrusive and definitely a tight fit. You'll see in my open shot the front right one isn't clipped in. I couldn't make it go in either. I had to remove the case and put it in that side first. Here's some pics. I got it for $6 shipped on ebay. The Seidio for comparison. You can see around the flash, volume buttons and speakerphone. It's definitely thinner.
