Sony DSC Cybershot P-XY Memory Stick Covers

[meenanath]

HI All,
I just got a DSC P-72, I find that the memory stick cover seems to be rather delicate. It seems to have a couple of plastic wedges which serve as stoppers. However, incase a user plans to swap multiple memory sticks or use a memoy stick reader to transfer files -- I think it won't be long before those notches wear out.
Any experiencs with the Sonys regarding this??

Concerned user.
