After seeing multiple YouTube reviews of the Speck PixelSkin HD, I may just keep mine. We'll see until it actually arrives and if I change my mind. I can't really judge it until I hold it in my hand.
I didn't like the pictures of the case early on, but it seems in the videos that it will grow on me. The front part is similar looking to the bumper. The "PixelSkin" is the one that looks too bulky for my taste. The PixelSkin "HD" gives me less paranoia with the glass back even it covers it all except the camera/flash. I can be a bit more rugged with my phone and less anxious if I happen to drop it on concrete then if only with a bumper on. At least one side of the glass slab (the most shatter prone) gets completely protected and nomore applying fingerprints on that side either. Extremely pleased with my choice because clear hard cases suck, in my opinion. Scratches and showing lint gets me all OCD sometimes. With the black bumper already in hand, my choice looks to be an excellent alternative and even an upgrade to my bumper in some ways.
Got something to look forward to in September.
