The home screen has also been redesigned to reduce the amount of wasted space presented by increasing the density of the icons displayed. In addition, the home screen is populated with widgets, the kind of which you'd normally find in the notification center, which can be expanded and run alongside other apps. Integration with the Pencil has also been improved with its latency dropping from 20 ms down to 9 ms.
Apple announced during the keynote that it intends to bring "desktop-class" web browsing to the iPad with improved web-app compatibility, as well as new keyboard shortcuts and a download manager for Safari. Most impressive, the iPadOS will now support external storage including thumb drives. Just plug one in and open the Files app.
Developers will be able to download a preview of iPadOS starting today from the Apple dev portal. The public beta launches later this month and the public release is scheduled this fall for iPad Air 2 models and later, iPad 5th gen and later, iPad mini 4 and later, and all iPad Pros.
