I've had the InCase slider for my G1 Iphone and the Griffin faux-leather case for the Iphone 3G. The matte finish came off very early on with the Incase for the G1, and from the forum posts it appears it is also doing so for the 3G. I liked the Griffin case, but after awhile the faux leather started coming off. I picked up the Neo last week and I'm pretty happy with it. I think the rubber lining will help keep stuff out from under the case and reduce the likelihood of scratches. I think the case is pretty solid and well designed. Yes, it is a bit of a pain to put on, but once its on it does a great job of protecting the Iphone-even around what would normally be exposed areas with other cases. Again, the silicone lining really helps minimize exposed areas.
As far as the logo on the back being raised up and causing the phone to wobble a bit, I think it actually makes the phone a bit easier to pick up, and will likely help reduce scratches because less surface area is being worn when laying it down.
So far so good. I'm happy with it-and I'm normally pretty picky about these things.
