| Did you mean that backwards? If a microSD doesn't have fins
| and the slot has additional space for fins, how would it
| prevent the insertion?

| to enter.

| PRO, Memory Stick PRO Duo, SecureDigital (SD), etc.
|
| Why is there now a need to have non-rectangular cards with a
| weird organic shape on it?
|
| EDIT: I see now that the fin is not like an appendage added
| to the microSD form factor, but rather a subtraction from its
| shape. The form factor makes a lot more sense after seeing
| the image shared by kevin_thibedeau.

| Transfers with USB-C cables takes ages (USB2).

| AirDrop occasionally removes live photos, converts into

|
| iCloud works so-so. Order of magnitude slower when compared
