think we're saying the same thing ED, I was just saying that since everything is ran in GPU on android, the fact it's one way or the other probably doesn't matter much performance wise because the whole system is effected basically the same. But when compared to directFB it costs a bunch as we both said.
I was reading a thread where a guy was comparing latency frames in a GBA emulator on multiple platforms and tracking input to output and the pandora is 5 frames of delay where the average android is 7 frames and native non emulated being 3 frames. From using android devices myself there doesn't appear to be any significant increase running in portrait over landscape YMMV. But clearly there's a benefit of not using GLES for the purists out there. While the hit isn't as significant as doing everything in CPU it seems, I would agree running everything in GPU effects battery as well as the added bit of latency.
