“Nobody cares” is how Linux will eventually win on the desktop. It becomes viable for most people when they no longer “need” whatever they were using before. As Linux is free, it will win when it becomes “good enough”.
The largest barrier is the fact that the end user is expected to install the OS themselves. Having an OS work 100% of the time right out of the box with a default install is impossible. Windows and OSX have a huge advantage by being installed on the factory floor. The manufacturer guarantees that the drivers work for the hardware they decide to install and that the default applications on the OS work as they should.
Linux needs an equivalent to Microsoft or Apple that can put Linux on shelves at WalMart for average people that buy $600 desktops.
