First, a disclaimer - I have been using Linux for many many years and things that most people consider difficult or obtuse are easy for me. So any statements about Linux's ease of use should be taken with a bit of salt.
So I bought my Lenovo Legion Go with the full intent to dual boot with Linux, and I couldn't be happier!
Nobara Steamdeck Edition was really easy to install (relative to other linux distros) and 90% of the device's features are working without doing anything else.
However, I'm a bit picky so I swapped out a bootloader that supported touchscreen selection (rEFind), and found a wonderful guide that brings the functionality almost to parity with Windows (and actually superior in a few ways) - https://github.com/aarron-lee/legion-go-tricks
The end result is something that feels better to use than Windows. Nobara running in "Gaming Mode" (Big Picture) uses only 1.6GB of barely breaks 2.5GB with a third party launcher running. This means that setting the UMA memory allocation (Vram allocation) to 8GB works a lot better! Even launching into "Desktop Mode" provides a better experience than Windows 11 in many places - mainly resource usage and responsiveness.
Ultimately, I'm considering shrinking my Windows partition to be only used for Firmware and Bios updates going forward. Linux provides that good of an experience for me.
Linux still probably isn't for the non-technical quite yet, but in a year or two, it might be! In the meantime, if you like to tinker, consider this an enthusiastic recommendation to give it a shot!
