Oh no, I wouldn't use the BROWSER in portrait mode, but some other apps are better in this mode than landscape. Such as music playback... Holding a device in portrait is more comfortable and better still, having the flip ability can also allow you to use your hardware buttons in EITHER hand.... Not just the left! Re-mapping buttons globally is also a great feature. EDIT: The sales channel has no mention, nor does the Nokia site itself, of a non-consumer target audience. Most people don't go to tech conventions.
