Apple has higher-end Pro models starting at $999. The new iPad Air has several features found in older Pro models, but not the latest. For instance, the iPad Air has a home button with a fingerprint sensor, while the latest Pro ditches that to make more room for the screen.

Apple is also refreshing its 7.9-inch iPad Mini for the first time in more than three years.
