I have a different Opinion: The Pyra is not a Retro Device, but a Future Prov Mini Handheld Computer, and as everything becomes Retro soon or later, its quite usefull for it to get faster over time whit new CPU Boards, when the Pandora was up, the DS and the PSP where not that long ago, and i can remember that i played still PS2 not long ago then, so emulating them was not neccesarry..
Next Year, the PSP is 10 Years allready out of marked, so whe can call it also Retro now, ..
So to accomunate this fact, that whe will get new Retro System that will be cool to Emulate, the Pyra CPU will have to evolve over the next few 2 Months (tm) Cycles..
Also the Pyra is meant to be long time Service, so if i will get burry whit my Pyra in hopefully more than 100 Years, i dont think i want it to be still 2 x 1,3 ghz Omap5
