As another commenter said, seedvault is a huge part of it. That, and when I am taking video to upload somewhere, it would take forever to transfer a 20-120 minute 4k file. And file transfer isnt the only reason. Android 16/17 are bringing desktop docking features, and thats s feature I’ve wanted on phones since Android 8. I have a device with DP out now, and as someone who owns a dock its a game changer for events where I need to display to something fast. I can’t wait for it to be a fully fleshed out DE. (Not to mention the fact that Chromecast is a shitty format that my is doesnt even support)
