As far as I have seen RIM has been pretty quiet about the portrait orientation on the BlackBerry PlayBook. In case you don’t know portrait orientation is when you hold the PlayBook sideways like a traditional book or a Kindle. RIM has been saying that portrait mode will be available on the PlayBook and switch quickly but it has been disabled in all of the video demos I have seen to date. I am not sure if this portrait mode has been shown by RIM before but this is the first I have seen of it. Let me know if I am wrong!
A friend pointed out to me that at some point in time RIM has updated the BlackBerry PlayBook landing page with two new renders that show the PlayBook in portrait mode. I think the week view of the calendar looks hot and definitely is reminiscent of BlackBerry OS 6.0. The second of Kobo does not really show much new since it is a 3rd party app. Still its nice to get an idea of how it will look. Hopefully it transitions between the modes seamlessly with its dual core processor.
