The nice thing is that Linux is always improving and Windows is always in retrograde. The more users Linux has, the faster it will improve. If the current state of Linux is acceptable enough for you as a user, then it should be possible to get your foot in the door and ride the wave upwards. If not, wait for the wave to reach your comfort level. People always say <CURRENT_YEAR> is the year of the Linux desktop but IMO the real year of the Linux desktop was like 4 or 5 years ago now, and hopefully that captured momentum will keep going until critical mass is achieved (optimistically, I think we're basically already there).
