Wow, I didnt know the Neo Geo X had an Opendingux port, thats amazing. Too bad you can't find them for under $200. I'm also not a fan of the fact it only has an Analog stick, and no Dpad
I've read up on the Pyra. I'm not interested. Far too expensive for what I'd be using it for (GBA, SNES, MAME, etc).
I've been considering finding a 3.60 Vita, and that is probably what I'll do if there is not a new "turn-key" emulation system announced in the next while.
