You might be able to install Android x86 on this, and use it however you would use a typical Android box. Another option is libreelec.
If I were you, I would install Nobara or Bazzite, the HTPC version. Which can boot directly into Steam Big Picture. You can install Jellyfin client, add the TV version to steam and you can launch it with steam big picture mode, and Jellyfin's Linux version of TV mode supports gamepad navigation. For Android apps you can install Waydroid and use whatever android app you need, like SmartTube. It might be a bit time consuming to set up, but it will be way more versatile, as you can easily just boot to desktop mode and do other things as well. Plus, you can play games. Emulated games would run great on this device, you can use something like emudeck or retroarch.
Mailbox provides aliases for free, meaning emails of both [email protected] and [email protected] will come to a single account.
You would need to buy another account in order to keep both of them separate.
