The way we interact with our Mac is fundamentally different from the way we do with our AppleTV. The iPad interaction interface is different from the Mac but not fundamentally. AppleTV is first anf foremost an entertainment device, the Mac a production device. The 12.9/13 iPad Pro is suitable as both for enough applications that benefit from dual OS flexibility. The Mac-like additions to iPasOS 26 make perfect sense to me. Keep it up, Apple!Apple sells it as a complete, customized solution for the best experience.
It's the same reason Apple TV doesn't run macOS. Fundamentally, it's the same box as a Mac with HDMI out.
