Back to the subject: I really don't see why people shouldn't use Linux.

1. Most users know nothing about Windows so both OSes are an equal mystery to them.

2. Most users don't consciously interact with their OS, only with the applications that run on it. Sure they learn how to navigate, save, print and so on, but those tasks should be trivial under any OS.

3. The big problem is getting skilled people to do the setup and provide support, particularly out in sticksville, like here.
