I like to keep my iPAQ PDA handy, so I've taken to putting it in my shirt pocket since my other pockets are full of keys and coins and other sharp little stuff (LEGO pieces, paperclips, etc). Unfortunately whenever I lean over, the PDA goes slipping right out and crashes to the floor. So far it has kept functioning, but the screen got a big ding the last time this happened.

A holster seems overkill, so I'm wondering if some kind of rubbery clings on the back might help... Anyone else solved this problem?

cheers- Scott
