This product is baffling. The original nVidia SHIELD's competitive advantage was the built in controller. Now they give you a tablet and a wireless controller. Just like ANY other tablet out there already. With all of the same problems. How do I play on that tablet when I'm on the train or bus with the controller? Balance the tablet on my lap? I tried that with my Nexus 7, it doesn't work worth a crap. I don't play GTA 3 on my N7, not because it can't handle the game, but because using a separate controller with the tablet is a logistical nightmare. SHIELD v1 solved that problem, and now v2 re-introduced it. I don't get it.
I don't play games that I need a controller for on my tablet. Thought it would be cool, but seriously? No.
There is enough decent games that have an interface that works great with tablets. Anything else I can play on a handheld or my computer.
