I still can't get over the fact that Apple raised the price on the mini. They almost always introduce the new model at the same price as before. So the lineup as they head into the holiday season for the low-end 16GB WiFi models is: $299 for the iPad mini, $399 for the iPad mini with retina display, $399 for the iPad 2 (which they're continuing to sell as their low-end iPad), and $499 for the iPad Air. Price wise, I think the best deal is the new iPad Air, and I can imagine it'll be a big seller.
Overall, it's fantastic to see the new iPad Air and iPad mini move up to the A7 64-bit processors. This will likely make them the fastest tablets in the world. The mini apparently didn't get the M7 motion coprocessor, but I'm glad to see it in the iPad Air.
Apple showed a video of all the amazing ways people are using the iPad. I'll post it later. They announced there are now over 475,000 apps custom-designed for the iPad. No other tablet comes close—probably in the tens of thousands. And many of those apps for other tablets are just phone apps stretched to tablet size.
They also announced that over 170 million iPads have been sold, making it one of the most successful products in the industry. But even more important is that people actually use their iPads. Apple said that they're used over four times more than any all other tablet computers combined.
