A note about the polls: as another one who lived in Taiwan (yes, Taipei, though I roomed with a dude from Kaohsiung, who was pretty green): Supporting the status quo does not mean supporting independence. Among virtually all supporters of the status quo, they support maintaining it until reunification is in their best interests.
That is, once mainland China catches up to them economically, and the human rights/democracy situation in mainland China improves to the points they aren't worried anymore, then they get a sweet reunification package, and reunify on (mostly) their terms. May take another generation, but time is overwhelmingly on China's side for this one. Most young Taiwanese- even in the south- speak Mandarin over Taiwanese. In Taipei, most people can't even speak Taiwanese (except to swear). Even in homes that speak Taiwanese, Mandarin is the language of school instruction, and as Mainland China's influence grows in Chinese pop culture, the next generation thinks of themselves as "Chinese" rather than "Taiwanese." Hell, even my Taiwanese roommate was happy to refer to himself as "Chinese" (in the cultural, linguistic, and ethnic sense; Huaren, Hanzu, etc).
Taiwan is complicated, but the GP was right when he said a majority of Taiwanese favored reunification. It's just that the majority favor it much, much later, not now. Noone in the Taiwanese government, or really noone other than a few extreme "nationalists", advocate for Taiwanese independence or consider it a realistic possibility. It's more or less an accepted fact- but "hey, no rush, let's wait til we get something really nice out of it, and have guarantees from a Chinese government we can trust".
But yeah, most of the people who want "immediate" reunification are Waishengren who came with the Nationalists in 1949. And Taipei is hardly representative of the "Nanbu". But hey, it is still the economic, cultural, and political center of Taiwan. And it rocks; I recommend the best eel outside of Japan, a place called "Feiqianwu" in Zhongshan district, right up one of the little red light alleys. You've got to wait in line to get in, but damn, that stuff is goooood.
