I don't even want portrait mode at all. I disable it in all apps that have it like gpodder and conboy and turn to launch phone cause the device gets mixed up at times.

Apart from not switching to portrait mode correctly I don't want it cause portrait's real use is one handed operation but I find the device too fat to use with one hand especially with the resistive screen meaning I have to use my nails. For me it is just impossible or burdensome to operate with one hand.
