What I really appreciate is that it’s geared toward handhelds, but has a decent desktop experience and is powerful enough to be a nice mobile media/piracy box with a remote and a USB-C breakout dongle. You don’t even need to change the read-only filesystem if you use WireGuard VPN (this might take some legwork to generate the .conf files you need, depends on VPN provider) and a streaming/torrenting program that comes in flatpak.

EDIT: Also forgot, you can add a custom shortcut to your Steam Library and have (some) programs launch from the SteamOS frontend rather than desktop.
