It's not a handheld though is it? it's a both hands hold huge tablet.
I've said it a few times but basically I already have a 7" tablet with a controller that I carry around when we go on holidays. It needs a case, a case for the controls, a case for the batteries and charger etc. It's a pain, basically. This is too big to fit in your pocket or be properly portable like the older Nintendo handhelds.
What made Nintendo successful was getting it right. I remember when the Gameboy came out. Oh how I laughed, given I had an Atari Lynx. However, I soon ditched my colour display and stereo sound etc for prolonged battery life and ease of carrying.
I just think this thing has fail written all over it. I mean, it's assuming you carry a bag with you everywhere you go. Otherwise how are you supposed to carry it? And if it's a console it's woefully under specced too. Jack of all trades, master of none comes to mind.
