Several days after the launch of the new iPad 3, HD, or whatever it’s called, we all know about it’s blazing 4G capabilities, including its ability to be a hotspot, carrier permitting, of course. We know about its Retina display, which makes the painful, insufferable scourge of image pixelization a thing of the past. We know about Infinity Blade. We know that to pack all this in, Apple’s designers had to let out the new iPad’s aluminum waist to accommodate some unfortunate but really quite microscopic weight gain. We know the iPad’s battery life is still amazing, and its price point is altogether unchanged. We know Apple has adopted a cunning new strategy of putting the previous-generation iPad, as it did with the iPhone 4, on a sort of permanent sale, to scoop up the low end of the high-end market. (We wonder if this was Steve Jobs’s last decree or Tim Cook’s first.) We know a lot about the iPad.
