I own old Chromebook.
Chromebook software updates are not forever.
It is my understanding that some Chromebooks might be locked in such a way that installation of Linux might NOT be an option or the might be a high chance of bricking the device.
At least that was the case with my Chromebook.
So, once OS updates are unavailable, the machine might become a weak link from security standpoint or stop running some software.
Chromebook is still a great option, but be careful with very old ones.
Take snapshot. If problem occurs, manually change boot label to use snapshot label.
BTRFS is zero effort on root, because it is included in kernel. ZFS on root is extra effort at least on Arch, due to licensing restrictions.
Dedicated gaming machine or dual boot is a way to go.
I played steam on Arch and one update of OS and game stops working.
Despite claims, Windows gets better outcomes. I played a lot of World of Tanks Blitz and the same hardware on Linux was significantly lower graphics quality and FPS compared to Windows.
Windows is better for gaming than Linux.
With Linux you have to be ready to play only what works.
Great illustration.
Whatever are those options?
