This is in the rumour mill as there isn't enough information or evidence to validate the existence or features of the GA380.

You will need to translate the page.
Points of interest:
Looks pretty slick, nice design and it has an analogue pad.
Suggestions that the device can play PlayStation 1 games and wait for it... N64 games.
Suggestions of a Wi-Fi connection with internet access being possible.
True HDMI support/output.
CPU speed is listed at 500GHz which obviously is a typo, guessing they mean 500MHz with the ability to overclock to 600MHz.
The article is dated from last year and I wouldn't take anything in it seriously. I fail to see how a device with a 500MHz CPU can effectively emulate the N64. Still, fun to talk about and dream.
