i do feel the ecosystem isn't broad enough for linux to become consumer facing. E.g., if you buy a random chinese made writing tablet and tried using it on linux, it has less than even chance of working straight out the box.
Similarly with bluetooth, wifi (for laptops), etc.
The problem is that OEM are locked into windows, so you have the chicken/egg problem where OEM won't want to spend effort on linux compatibility without a large customer base, and customer base won't grow unless they know for sure it is always going to work for _any_ piece of hardware they might purchase.
May be steam machine and valve could be the push it needs to establish a large customer base.
