I wonder what the stereo width and image is like. Would you have to have your face right next to the phone to notice the stereo? With such a small device, being slightly out of alignment with the device will mean the difference between good stereo image and muddy mono-ish audio.

In the keynote they showed stereo in the landscape configuration. They didn't talk about the portrait configuration. This is why I'm guessing that they might have stereo in portrait too, instead of stating it as fact.

that you can immerse on water.. :-)
