The only reason I haven't fully swithed to Linux at this point (because I'm very comfortable in it) is that my work pretty much requires it. Having the enterprise world in a strong hold to the point where important industry tools simply have zero/very weak Linux support feels like half the reason the fabled "Year of Linux Desktop" hasn't come to fruition. Many engineers and artists literally cannot afford to switch. Many other industries have too much data in servers or spreadsheets to efficiently move over.
