What is all the fuss about a second analog on a handheld? Why is it so important?

I don't think people are really mad about the 3DS not having a second analog stick but more with the fact that Nintendo would introduce one only a few months after launch with rumors of a redesign circulating. That is what has me miffed. That Nintendo would screw over early adopters like myself in such a way that the only way for me to play with dual analogues is the buy the new version of the 3DS or an ugly and bulky add-on.
