Originally I thought this was because Zetsu had managed to save Madara using his body material after Madara was "killed" by Hashirama. However since we now know that Tobi created Zetsu from Hashirama's cells we know thats untrue.
Something I found really interesting was Tobi's interest in Edo Tensei. He wanted every little detail. I think this may have been because a few different reasons. First, it could have simply been a method for Kishi to fully explain how Edo Tensei worked. Second, it could have been because he felt threatened by it. Third, and what I think may be the right choice, is that he wanted to learn its secrets so he could us it for himself.
Maybe the body he is currently using is imperfect. We know that hes been referred to as a shell of his former self, so theres certainly something missing. I think its possible that this "cloned" version of Madara is currently soulless. And this is the problem. A "shell" is something that appears whole on the outside, but is empty on the inside. This would be a perfect metaphor for something which is soulless. I think that maybe due to the cells of Madara being a part of Tobi, his thoughts and memories are still intact. This is why he refers to himself as Madara, because in essence he is Madara.
This also explains the final coffin of which Kabuto raised. If what I previously said is true, its very possible that Kabuto raised the soul of Madara and is holding it as a bargaining chip. Kabuto knows that this "Tobi" is a soulless version of Madara, and he knows that in order to become complete Tobi needs to regain his soul. As long as Kabuto has the soul in his possession, Madara is at his will.
And this is why Madara was so interested in Edo Tensei. Its the jutsu he needs in order to reattach his soul to his body. Hes trying to learn how to use the technique so he can bring back his soul, and once again become whole.
