I liked the proof on the site that broke it down into a summation. Basically, .9999999... can be rewritten has the sum from n going to 1 to infinity of 9*10^-n. That can then be rewritten as the limit has n goes to inifinity of (1 - 10^-n), which 10^-n going to infinity is 0, so it equals 1. Seems simple enough, and there aren't any weird assumptions.
I was however, under the impression that it was not equal before reading that site.
