A quick release from NVidia today says that they've lowered the price of the SHIELD from $349 to $299.
...we’ve put SHIELD in the hands of thousands of gamers....And their reactions have been more than just positive...They’ve helped us build a better product. We’ve heard from thousands of gamers that if the price was $299, we’d have a home run. So we’re changing the price of SHIELD to $299. If you’ve already pre-ordered SHIELD, you’ll be charged the new, lower price. You will only be charged $299 when the product ships.
So, some good news there for those both on the fence and who have already preordered the device. That extra $50 could go a long way in the Play Store.
