I do like the feel of the portrait-side swiping on the N9, but I think it comes at a compromise. It uses space up that could've been more screen.

It effectively shaves off screen estate from both edges because of the 16:9 proportion. It makes videos that much worse. Or browsing that much difficult. Or reading that much more frustrating.

I think on a mobile device each 1mm is precious, whereas on 10in tablets you can get away with some "flaws" and even moreso on a 13in laptop.
