Earlier quoted context omitted.
Heh, I guess. My last two phones had the jack at the top, so it's instinctively where I put it. I do like being able to rest it on a surface while holding it vertically with an audio cable connected. But charging it at the same time from the other end is a little weird. I guess in an ideal world I'd put both ports at the top, but I don't think that's what you were going for :)
Top is the right place unless the fone flips itself. Or playing audio in a car is a pain. Even keeping a phone charged in a car is annoying now.
I put my phone into my pocket with the same orientation that it's in my hand, while using it. Hold phone, rotate arm down, stick in pocket. The phone is now upside down in my pocket. If the headphone jack were on the top, you would have to flip your phone first, when putting it in or pulling it out.
