if it ends up doing Amiga games fullspeed with a proper functional emulator (none of this uae4all crap) i would consider it at the price it is.
however, i'd imagine any decent mips core could be used for PSPUAE, this thing doesnt have much more power (and the spsp should be able to use the media core thing anyway), and the fact that it seems so much like a DS (which is so flimsy and pathetic it's laughable) really puts me off.
I'm certainly not buying another device just for speccy emulation. At least the DS can do that, and with a keyboard.
