@DrJLecter so, installing Linux was difficult, but have you ever had to perform a fresh install Windows or Mac OS? Having installed Windows and Linux hundreds of times, I'd argue it's quite a lot easier to install a good Linux distribution (Ubuntu is not my favorite, but it's Good Enough) than Windows on a new PC, but you never see that because 90% of new PCs sold have Windows preinstalled.
There are systems builders that preinstall Linux, for what it's worth.
