Agreed. Taiwan and China have been and continue to move together economically. The political conjoining will take longer. Once MAD (mutually assurred destruction - through economics) is established and some time passes, they will have enough in common to join in a one country, 3-systems manner.
The independence stuff in Taiwan comes from a release from a fairly authoritarian form of government. The higher educations and political reforms in Taiwan combine with the reduced expectations of prosperity to foster an environment where many of the old ways are questioned. The politicians are learning to tap into that.
Taiwan still has one of the most corrupt policital systems around.
