Can anyone explain how to use the described screwdriver trick to pop the case off, without damaging the plastic. I don't know how many times I've tried to be so careful (with whatever it is I'm trying to take apart) and end up putting screwdriver dents into the plastic. Obviously it looks like crap afterwards.

What would be nice is if someone would come up with a case cracker like used to be available with old one-piece Macs (Mac Classics and earlier). From looking at the illustrated mods, I'm not sure it would work with so many plastic latches.
