Nvidia will probably be even better supported in the future and opensource drivers are getting close to proprietary feature sets.

Wayland support has also been improving in major ways so we can have fractional scaling, HDR and all those nice things soonish.

Then in general there will be an even bigger push for games to support Linux via DXVK, Wine etc to support Steam Deck.

I would recommend trying out dual boot setup for a while and then deleting Windows when you’re ready.
