The nice thing about the SCDS1 is the SD card doesn't lock in place. So if you're worried about the spring breaking, just insert your SD card until it clicks and then from there on if you have fingernails just slide the SD card in/out of its slot. It comes out fairly easily and you'll never have to worry about the spring breaking if it's permanently depressed. But as a fair warning, should you ever take the SD card out by pressing it down to unlock the spring be certain to keep your finger on the top. Otherwise it's gonna launch that sucker out like a cannon. I almost lost my SD card once on the bus when my finger slipped and it shot out under a seat.
But anyway if it worries you, you could always purposely break or if there's a way, remove the spring from the slot on your own. Personally I've thought about this myself as while the spring is a nice perk, I'm always worried that a slight bump might send my SD card flying out somewhere. It seems to hold the card in firmly on it's own but just enough so you can still easily slide the card in/out with little trouble. So to me the spring almost poses a liability. Then again I'm not sure if anyone's ever ran into that problem on their own if they're careful...
