I picked up my new Touch yesterday and got one of these to go with it:

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.
