Hey Folks-
After doing some research and following the forums I had decided to get the Invisible Shield full body shield for my wife's Treo 600 and I opted to get the Invisible Shield screen protector for my Treo 650. My wife is a little more carefree about handling her Treo than I am -- hence, the full body protection for her 600 from the potential scratches.
Once I receive it and install it, I will post my comments/opinions about this product. I don't think I've read anywhere on this board about the full body shield -- maybe I'll be the first?
