Hi.
Both considerations have coherent foundations, so I'll tell what I do.
It is a fact that the modules where not actually made to be inserted and removed every single time they are requested and then not needed at the moment, so plugging and removing modules too many often will surely cause abrasive, frictional wear with time. SO, keeping modules in place (and avoiding continuous replacement) will keep contacts in good shape for longer.
The card reader itself is a different breed, it not only uses the port contacts but also 'grabs' the calculator with the two plastic clips. Once it is attached, any torque over the card reader body having the calculator case as a reference system reflects as extra pulling strength on the bolts found in the top of the calculator body, closer to the LCD. Hence, depending on how the calculator is pushed, bent or twisted (urgh!), posts will suffer harder if the card reader is attached.
I plug it in only when I need to use it, I do not often leave it connected. And if needed, like when you need to run a program with card reader functions, I try to keep it in plain surfaces, transportation avoided as possible.
Hope this helps a bit.
Cheers.
