this looks pretty useless to me. Just like an above poster said, the case is made of a plastic that will shatter and crack upon impact and will not be a very good protector for the SGS.
Another thing i'm wondering is, what's the point of this sliding mechanism? I mean, if the case is meant to be on the phone all the time, is the sliding feature only good for removing the phone? If so, i don't see the point for an extra feature like that when we can just remove the phone the conventional way like with most hardcover back cases.
If the case is only for storage, like when you put it in your pocket, and that you will remove it when using it, wouldnt a leather case pouch be more practical and offer better protection?
Just my 2 cents.
