Ok, I'm not gonna use reasons that you've already heard before, although many of them I feel are legitimate. We must first come to a basic conclusion. It is almost without a doubt that Tobi does not posses ms. For starters he has never not once even had it active. I'm not going to question why he would never use it if he had it, because somebody would give a ridiculous answer about not needing it or wanting to hide it. Instead, lets look at actual ms user tendancies. I don't think that we've ever seen someone who possessed ms ever not use ms. I'm just saying that this makes me seriously doubt he possesses it but at the very least confirms that it is not a character we know who has/had ms. That brings us down to 4 possible options. He is either Obito, Kagami, Hikaku, or an uchiha having been completely unaccounted for. The later I think we can skip because of the fixation the manga gives on Tobi's true identity. Although not entirely impossible, I believe it would be impractical if we have not seen at least a little bit of the shinobi who became Tobi. That brings us to Hikaku, who, while not that practical considering his name was not mentioned except in a databook, was an uchiha possessing only the three tomoe sharingan, and to be fair he is a option for Tobi. Now for a more reasonable option, Kagami. While he is not a very large or main character, he was mentioned and given a role in the First ninja role. Kagami gives an acceptable age, a sharingan, and, having been a part of a war, a mental break could have caused a twisted mind frame that Tobi seems to have. Also his hair matches. Also, Kagami does not have a specific description of when he died, so that he survived as Tobi is not impractical. Now here is I think the most practical, obito. He has no ms. Unlike all the other options, Obito has an actual need for the reconstruction seen in Tobi, seemingly white Zetsu like arms. Although the lack of one sharingan is a problem, he seems to know very well how to remove an eye/dojutsu, so it is possible he, having said he helped Itachi I believe, could have taken one during the uchiha massacre. Obito also knew enough about minato's TS ninjutsu to devise a plan against it before having seen it again in combat, which might have come from Tobi's first hand experience. Obito "died" during the third shinobi war and so was probably close to the hidden rain. He could have gone there after revival, putting him at the place where he supposedly convinced Yahiko to found akatsuki and the place where he helped awaken nagatos rinnegan. This list should be enough. Of the three named options, Obito is the one who produces the most connections. And lets not for get the obito to Tobi anagram(after taking out one O).
While the other options are practical, obitos need foe reconstruction, lack of ms, and placement have me convinced that Tobi is either obito, nameless uchiha' or random eye stealers. But because of the fixation put on tobi's identity, I think it can't be just anybody, and therefore has to be either Obito or Kagami.
