I don't expect that iPadOS 15 will solve all problems of the platform. Even if Apple allows true multitasking there are still a lot of work to be done, if the iPad is to be seen on par with the Mac. Simple put it, we need full blown enterprise apps, that are on par with their desktop equivalents:
- Microsoft Office
- Adobe Photoshop
- Apple iWork
- Apple Pro Apps
- Adobe Premiere
- Microsoft Teams
- XCode
- Parallels & VMWare Fusion
- Safari with full extension support
- Chrome with full extension support
Also, many of the default Apple apps must get a major overhaul:
- Apple Mail must get Smart Folders support
- Photos App must get feature parity with the Mac app
- The Contacts app must also get feature parity with the Mac app
The iPad is a great device and I enjoy surfing on it or listening to podcasts or watching a movie, but apart from that I don't use it.
