It peaked at 4.05% in March. The last 2 months it went just below 4% as the Unknown category increased. For June the reverse happened, so 4.04% seems to be the real current share of Linux on Desktop as desktop clients were read properly/werent spoofed.
If you’re hesitant to fully commit at first, I also recommend dual booting with Windows. Over time you’ll use it less and less until one day you feel like reclaiming the disk space.
I have a 10 year old laptop that I had to get rid of the hard drive for and am installing an nand drive and want to use to re-familiarize myself with Linux on it. Especially since my main desktops are too old to upgrade to Windows 11(not that I’d want to anyway) and I figure going Linux now will save me from scrambling when the pooch gets thoroughly screwed after Win 10 updates end.
