It seems to do exactly what I want it to do:
Offers some impact protection-- not as much as other cases, but I'm pretty careful with my stuff.
Comes with clear and anti-glare screen films
Adds virtually no bulk to the device.
Slides easily in and out of my pocket, but has a rubberized back for good grip
Does not detract at all from the looks of the Touch-- I got the black one and it adds a sort of stealth look. The fit is excellent and the case looks like part of the Touch, not something added on afterwards.
No, the case is not under a screen. That said, I am using the invisible shield which has already proved invaluable. All in all, I've spent a fair bit to protect this unit and it still looks pristine. Definitely happy about that.
