The best time to play with Linux as a daily driver system is now.
Play around with some virtual machines using VirtualBox for instance, do some installs, try distros, try desktop environments see what you fancy. Cool thing about playing with VMs is if you tank a system you can just delete and start over. :)
An old laptop to try a real “bare-metal” install to play with is even better.
This way, when MS says “Win10 is gonna be left to rot as security swiss cheese and your only option is Ai-enabled telemetry-infested account-mandatory nonsense.”
You can just comfortably jump to something you’ve already gotten familiar with!
The 'Deck can be used as a “real computer” too! It’s worth playing around in Desktop mode to just get used to how using Linux and KDE feels.
Wishing you all the best. :)
