You don't get it...
OGL ES 3.0 is no superweapon.
Think of how hard it is to emulate a 400/600 MHz console even on newer PCs with really good graphicscards.
Our Pandora has a graphicscard that is comparable to a decade old midrange card on a pc.
The Pandora itself has 600 MHz (I know, I know, but lets put it this way for comparison...).
So do you think you can emulate a Wii or Gamecube on a Pentium 3 with 600 MHz and a VooDoo 3 Graphicscard?
Don't think so.
Even if the Card could handle all the features of a modern card, it is still slower and will not magically make really demanding programs playable.
