I appreciate the enthusiasm Linux fanboys have about this. But ain’t nobody but the most tech savvy would even consider it.
Linux is not consumer friendly, it typically involves putting in a shit load of effort to get working with your hardware, the ones that don’t still need a ton of work to make “Windows-like” and compatibility is always going to be an issue.
Yes, there have been a ton of strides toward this dream situation. But without financial incentive, making things user-friendly isn’t going to happen. In fact, much of the Linux community prides themselves on having a “difficult” OS.
Once Linux can, by default, have an easy to use interface, can natively run Android apps and windows applications, and can work with a huge range of hardware, it will never take off. Linux might get a few points of market share due to some business applications finding Linux a better option than updating HW and windows build, but those companies are going to struggle and will be even more dependent on their IT staff for the simplest of things.
