Some belt clipped cases bother me when I sit in a chair or in my car seat. But I don't see myself wearing it with just a T-shirt and jeans. The black straps and case stand out a bit too much for me. Perhaps I would wear it with a black T-shirt, but I would definitely wear it under a jacket. Transfers weight to shoulders.
Large pockets hold a lot.
Straps hang lose once case is removed. Pockets won't protect the PalmPilot screen. May tend to swing if worn without a jacket. Let me know your comments on the BurroPak case.
