I agree 1000%.
Something about that clip makes it WAAAAYYYY too easy for the the case (and iPhone) to go bye-bye.
I had that case, and my iPhone, for about 3 days when it happened:

The case slipped off my belt while riding my motorcycle! I should note I had worn my Treo on my belt, in a holster, for two years without it falling off. The Belkin Slip Case fell off at least twice (the second time was in my car).
I took that case back pronto. It's an accident waiting to happen IMNSHO.
BTW: My iPhone was returned after that bike drop--and I didn't realize it was missing till I got home.
