In my region (India), for a while, there seemed to be plenty of laptops available with Linux installed as an option. Then again in the last few years that seems to have withered down to almost none, sometimes even if the same model is available with Linux in some other regions. I am not sure what changed. Perhaps some deal with Microsoft. The good part is that the fact that they do support Linux elsewhere on the same laptop configuration generally means its easy to get it up and running yourself even if it does not come pre-installed.
In any case, as an old-timer, it’s very impressive to me how much hardware Linux supports nowadays without any drama at all. Not to mention all the progress made in software especially in supporting Windows-only games, which is truly magical work by the Wine / Proton teams. As far as I am concerned the “Year of Linux Desktop” is here already since I can use it daily without missing absolutely anything at all from Windows.
