I look forward for the Shield review. I will ask my friend at US to buy and sent to me. On video above, seems shield really responsive, and quick load the apps. hope it good as it advertise. I have mogA pro controller, playing dead trigger , modern combat 4 and shadowgun really have different experience compared using virtual gamepad. The bad side of mogA pro, you need to run the game mostly using pivot app, some can do without it such shadowgun THD (my device nexus 7). But supported game (mode A) need to run using pivot or else pivot app wil exit back to your device screen and mogA Pro controller losing BT connection. To reconnect after this eror, you need to force close pivot app, and do all over again like first time connect mogA Pro. really annoying, IMO. so I think Shield with built in gamepad should not have problem (I hope). And one more thing, vibration (force feedback) not available on mogA Pro. it is crucial part that was missing on mobile gaming. hope it will available at future time. I don't know about shield, it has vibration hardware or not, if so, then just need software to activate it.
