I'm super excited for the new iPad mini with retina display, but I was thinking about it and I'm concerned that this iPad will suffer from the same issues that the 3rd gen. iPad suffered from. At the time, being used to an iPad 2 and going to a 3 actually took some getting used to due to the extra heat, weight, lag, and battery charging duration. I know with the A7 chip, lag on the new mini shouldn't be an issue, and the weight is more but not significantly more. However, I have a feeling that due to an unprecedented amount of PPI, this product will be run very hot and use energy up quickly - more so than any other iPad before it. I noticed that in Apple's description of the iPad mini retina's battery life they now claim "up to 10 hours" where as with previous iPad's many reviewers claimed to get somewhere in the range of 12-13 hours of battery life. It's smaller than the full size iPad, with the same number of pixels. On top of that, iPad mini retina owners will also have to deal with a tremendously long battery charging duration, if it is similar to that of the iPad 3rd generation. Obviously I don't know any of these things for sure, but I thought I'd just throw the idea out there and get everyone's take on this possible issue.
