Scenes from Apple's iPad Pro and Mac event

Apple CEO Tim Cook started things by announcing that the Mac's active installed base has reached 100 million users: "What's most important to us is in survey after survey, the Mac continues to be rated No. 1 in customer satisfaction by far," he said.

From there, Cook jumped right into new Mac hardware, starting with a refreshed MacBook Air. It has a 13.3-inch Retina display -- providing four times the resolution with over four million pixels -- with no aluminum bezel. "The No. 1 feature customers have wanted in a MacBook Air is a Retina Display," Cook explained, "but we've made the display better in every possible way."

CEO Tim Cook revealed that Apple has sold 400 million iPads since 2010 -- which he said is more than the entire notebook lineup of the biggest notebook manufacturers combined.

Apple also revealed an all-new iPad Pro with an edge-to-edge LCD "Liquid Retina" display, slimmer bezels, and Face ID (no Home Button). It has the same footprint as the previous 10.5-inch iPad Pro, but it now comes with an 11-inch display. There's also a new 12.9-inch version.

Apple said the new iPad Pro tablets support all the same gestures as the iPhone X line, and they are powered by the new A12X Bionic chip, including an 8-core CPU and a 35-percent faster CPU. The iPad Pros are designed to be faster than 92 percent of the portable PCs sold in the last year.

Apple unveiled a redesigned Apple Pencil alongside its latest iPads.

Apple is also updating its old Smart Keyboard, which is now called the Smart Keyboard Folio, to allow the iPad to sit at two different typing angles.

As for the new Apple Pencil, called Apple Pencil 2, it attaches to the tablet magnetically and charges wirelessly. No longer do you have to plug the Pencil directly into the iPad. Plus, tapping the new Pencil to the iPad Pro will instantly wake the device and launch the Notes app.

Going back to the new iPad Pro tablets for a moment, Apple said the 11-inch model starts at $799. For that price, you get 4GB of RAM and 256GB of storage. The 12.9-inch model starts at $999. They will be available from Nov. 7. The old 10.5-inch iPad Pro will now cost $649.

None of the tablets come with the new Apple Pencil 2 or Smart Keyboard Folio, as those must be purchased separately. Apple did not reveal pricing or availability for those during its show.
