Presumably better task switching. If you switch between several applications, fewer of them will be evicted from memory, so they'll come up right away where they were instead of relaunching when you switch back to them.
Nextcloud self-hosted to replace Google Drive.
I'm really reluctant to recommend Nextcloud. The software is buggy, it's not e2e encrypted, and you're liable to data less if your VPS goes down unless you're good at managing cloud resources.
For most people, a service is better.
If you're on Android, that's probably the most important thing to consider first. Just using a phone with Google Play Services gives up a great deal of privacy, even if you think you've turned all that off.
So, consider either an iPhone or if you're really serious about this shit, GrapheneOS. The iPhone is easier for average people, but GrapheneOS is more private and you have more control. Both are better than Googled Android.
For a Google Drive alternative, that's simple. If you're already using Proton, get ProtonDrive.
For Google Docs alternative, that's a bit more challenging. There aren't any direct competitors with full end-to-end encryption that are any good and also cross-platform.
I was wondering about games during the announcement — they didn't really announce much with regard to games at all, except that you can run chess or iPad apps and the like.
I figured that at $3,500, they probably avoided gaming because they aren't "magic" enough to justify the price point, so why talk about them?
This is why we can't have nice things.
