@aaronpk my DSLR has CFII... That’s right its sooo old it uses Compact Flash. But reversible connectors sure are an upgrade.
@aaronpk id say with sd cards its less youre plugging it in backwards and more the fact that every manufacturer puts the bastard readers in at different angles meaning that you have to peer into it with a big torch to try and determine which way this specific device wants you to put it in
@aaronpk i plug mine in sideways, to stop the bits from falling out.
@aaronpk We need reversible SIM cards!
