What common sense? The common sense that there's no way in hell this can function as a magsafe with the amount of length that is inserted into the device, and the fact that the pins make contact from the sides. The shape and insertion method make it impossible. So yes, it is common sense. How do you imagine it would slide out?
I think you envision how this plug works plug far differently than I do. I mean that small magnets would hold the male end in place once it had been inserted. I don't see how this would be "impossible". I do realize that it might cause some EM interference though.
How do I imagine it would slide out? Um... by pulling on it? I don't understand why you don't think that's possible.
Well, anyway, you're probably right that it's not anything cool like that. Someone else mentioned there are dimples to hold it in with a spring loaded ballbearing. That would be interesting too.
If you really want to think crazy here, people keep thinking that this is an any orientation device with dedicated redundant pins. What if it's not redundant but designed so the bus changes pins after a primitive orientation negotiation? lots of extra pins then to do great things...
What if this thing is actually some sort of Thunderbolt "mobile edition" bus? Well, that's extremely unlikely since it would alienate anyone with USB ports only, but I can dream!
