Interesting. And I see that it is in fact not interchangeable with the iPod connector. Still, it's pretty hard to imagine someone mistaking a Galaxy Tab for an iPad because of the USB connector.
It all adds up. Any one thing is not going to cause 'someone mistaking a galaxy tab for an ipad', But when you put everything together, not even the lawyer for Samsung could distinguish the two.
That is the stock galaxy tab cable.
