Oh great, a terminal in portrait mode. Ahahaha thanks for the laugh come on you can't be serious. It isn't even 80x25. Your font will be much smaller than in landscape mode.

You misunderstood the word designed. It means that the application is optimized for use in a particular mode (landscape or portrait or supports both well). On various of your screenshots you're actually missing information which is in supposed to be on the screen which is a big no-no in usability 101. Add to that the only situation where you are able to show such hidden information is the last which is a remote desktop (VNC, in this case). Well, that was true in landscape mode as well. No sane person uses LogMeIn Ignition on iPhone in portrait mode by default, and the use cases where such is preferred are very, very small. Although it is possible to do so.

None of the examples prove portrait mode is better or easier to use in their case. None of the examples are for finger/touchscreen instead they are for stylus usage.

And the screenshots you posted do not resemble ASR because the rotation is manual because Nokia N8x0/Maemo 4.x doesn't have accelerometer.

My Sharp Zaurus did manual rotation too 5 years ago, on Linux (Qtopia), actually out of the box. Means nothing.
