That doesn't change the fact that, at present, it is required in order to do certain things. People who blindly proclaim that flash 10 support is just around the corner are deluded at best and ignorant at worst, especially when they imply (like one person did) that developers care more about open source than proprietary platforms like Symbian and Windows Mobile.
This is uncommonly known (in the real world. Hi! Welcome to the real world!) as a vicious cycle. "x86 is a bad platform, but everyone uses it, so we need to use it too, despite the fact that there are better processors, until everyone else wises up" *some time later* "oh look, because we used x86, and everyone else used x86, everything written in the last little while is x86. I hope someone steps up and starts doing things right" *more time passes* "Oh, no one else has a brain! Why are they still using x86?"
Someone at some point has to step in to make the transition on behalf of everyone, and that will require sacrifices. Within time, there will be games for the ARM platform, because the platform for them exists. If everyone keeps producing x86, all software will be for x86. The software MUST follow the hardware: it's impossible to write software for a platform that doesn't exist.
One final counter-argument, one that you cannot possibly refute:
A) The Cortex-A8 is on the cusp of being able to emulate the x86 to a degree that most of the games you mentioned in your other thread would at least be viewable, though not necessarily playable at only 1 or 2 frames per second.
B) Your arguments are to show that a theoretical "Pandora 2" should have an x86.
C) You yourself have said that that would be several years away still.
D) At the rate of expansion, that puts x86 emulation at about 30 frames per second in 4 years (though probably less)
Therefore, in five years, around the time that a Pandora 2 would be coming out, you'll easily be able to play these games on it, even assuming it uses an ARM. Your argument that it *needs* to be x86 is dissolved.
