The first section, "Amazing Apps for iPad Pro", is split into five subcategories: Enhanced for Apple Pencil, Desktop-Class Apps, Powerful Multitasking, Unleash Your Creativity, Bigger with a Bigger Screen and Immersive Experiences. Apple says the section includes Apple's favorite apps "that take advantage of its expansive Retina display and astounding experiences."
The second section, "Great Games for iPad Pro", is split into three subcategories: Gorgeous Games, Fantastic Sounds and Big Screen, Big Fun. Apple says the section will help iPad Pro owners "get started with games whose breathtaking graphics, spectacular sound, and immersive features create incredible experiences."
Limited quantities of the iPad Pro are available at Apple Retail Stores in multiple countries with Personal Pickup available in U.S. locations. Online, 32 GB variants in any color are available for delivery on Monday while other configurations are available for delivery in late November. Smart Covers and Silicone Cases are well stocked in Apple Stores, but the Apple Pencil and Smart Keyboard are out of stock or in very limited quantities in stores and are a 4 - 5 week wait online.
MacRumors' sister-site AppShopper also has a running list of all the apps updated with iPad Pro support.
