Really, have you updated the Firmware. The Shield Tablet has been the only Android tablet that I have ever owned that actually didn't lag. I don't understand this crazy touch sensor issue, my touch panel works superbly. Battery, I get the same life than I did with my Nexus 7, about 6 hours with heavy use, 8 when being conservative. That's exactly the same battery life I've seen with my Samsung Tab Pro, Sony Z and my new Nokia N1. The only tablet I have ever owned that got more than 8 hours consistantly is my Nokia 2520. Sorry but I think you actually don't own one, you just compiled issues that some might have experienced in the past or have been posted as a news source, Nvidia would replace you Shield Tablet without issue if any of those issues actually plagued your system.
