I just received the Contour Flick in the mail, and I gotta say I'm liking it. Yes it's quite minimalist in its design, and yes it probably won't protect against drops worth crap, but I'm usually quite careful with my electronics. I just needed something to protect the back of the phone from scratches, and this does just that. I also like how my iPhone pretty much looks naked (adds very little bulk, glossy black finish).
What I don't like is the BSE front skin that arrived the same day. I guess I should have done more research, but just feeling its surface made me cringe. It's way too tacky to be on a touch screen like the iPhone. I'm not sure if it would be any different when it's applied and dried, but from what others have said about the back pieces I think it would be the same. I'm thinking I should return it for a refund and just get a PS Anti-Glare Film instead.
Also liking the Rebel. I'm just wondering how tacky the silicone would be. I've had a Belkin before the Flick and I really hated how much lint got on it, and how it never seemed to slide into or out of my pocket easily. If anybody could post a review when they get theirs in the mail?
