Default Wobbly standby button

Okay, maybe it isn't the most devastating kaiser problem, what with the drivers and all, but - is anyone else's standby button starting to feel a bit loose?

After 5 months use, my button's still working fine, but it's a lot spongier and, well, wobblier than it was. Should I be worried? Is it likely to wear out completely soon? Is anyone else concerned?

I'm starting to think I'm over-using it - is it wrong to be using standby so much, is there some way I can break out of the standby habit without knackering the battery?

Thanks for any suggestions on this important issue...
