Might be just me, but... terminal in portrait mode ? Having lines word-wrapped is far worse than having less of them on the screen. Web browsing ? Portrait mode means constant zooming, and it's easier to scroll than to zoom (this is the thing I hated most when using a windows CE machine). For me, at least, these two do not hold too much portrait appeal (I won't MIND having them but I wouldn't use them). But feel free to differ, ergonomy is a very personal thing anyway
