I think this might be a mistake on the part of Asus. As the article notes there are already four or five Android gaming consoles available. I don’t know the sales figures for each of them, but it seems like a crowded field already.
If Asus is going to be successful, they will need to stand out by setting the Game Box apart from the rest of the field. But I see nothing in the specs or design of their new console that would achieve that. It doesn’t seem to offer anything that Android gamers couldn’t get from one of Asus competitors.
