I am talking about on the iPad itself NOT in headphones! Yes I realize you could accomplish that with 4 speakers and rotate with orientation. But I think Apple will come up with a more innovative way to do it than that. They could use virtual techniques like in headphones on the device itself. Heck they could even integrate sound into the screen since Apple loves to put everything inside the screen anyway lol. I dunno, but there is a for sure a better more elegant way to do it than 4 speakers! But even that would be better than now.
And don't tell me it is not necessary. The current audio situation with one speaker is NOT ideal. I don't care what you say lol! And I think Apple completely agrees with me which is why you have seen them hire people to most likely work on that exact issue!
If you are happy with it as is then you have a very low bar!
