Well, I understand some of your points (by the way 1-4 was true) but even though i am starting to shift more to kagami than obito,there is still flaw in your arguments. Pertaining to 5, when somebody saves your life, you will probably be willing to listen to them. With promises of true peace, the same promises that tobi speaks of now, madara could have easily persuaded him to join his side. Especially since madara as a master sharingan user is probably great at influencing peoples decisions. Tobi believes that he is good as well. He has said time and time again that his goal is to create a world of truth. I would not say this is completely good, but it is certainly not completely of a wrong intention. Just as Nagato was used, Tobi could be being used just as much. I'm not saying that he is but im saying we dont know that he has evil intentions, just his methods are evil.
Onto 6, what evidence do you have that tobi taught madara about those things (i wont repeat them all)? Even if madara couldnt learn this information himself, there still is no probable cause that it was tobi who was the one who taught him. And why wouldnt madara know. Itachi knew himself about mangekyo, about izangi, and about izanami, and the entire story behind it. Unless Itachi was in cohorts with madara and tobi at some point, that would make this information maybe not completely available to everybody, but madara would have been able to figure it out. For your next bit, pretty much everything you said was due to his sharingan ability, his space time ninjtsu, and attained knowledge. He has shown no power, he has just shown extremely effective passive skills. Oh and the regenerative body parts I believe is a product of reconstruction from zetsu's white body. He was not stabbed in the chest ever. Minato put a tag on him not a kunai. Then he removed his control over the nine tails. Also the Rasengan was anincomplete jutsu at that time. it barely scratched most of him. It looked deadly but most of what it did was it put a whole on his clothes on the impact spot and it thrashed his body up. That is not a matter of tobi's strength, but rasengans weakness. Most of the impressive things you wrote on that list were due to his space time ninjutsu, so there is pretty much one factor you are considering in all those examples you listed. His power is completely unknown. All we know is that because he can become invulnerable and he has rinne and sharingan, he is effective. Beyond his space time ninjutsu hes had one taijutsu fight and that is the extent to which we know his "power". If even konohamaru had the power to be invulnerable, he would be an incredible threat to everybody. Although what makes it even more threatening is his manipulative force. He is manipulating and controlling so many things, and naruto and friends can fight the products of his persuasion, but they cannot attack the root of the problem. That is why tobi is so dangerous. Also now because he has the incomplete ten tails. Only now will we see his true power as he has to become vulnerable at some point in order to defend the juubi. So dont tell me how powerful he is until we see him actually do something. Even now itstoo late, because tobi has had time to develop some skills. Only if he does something completely absurd that isnt due to the rinne gan would I say that there is no way obito could have learned that in almost 20 years (since his boulder incident). All he needed to learn is one space time ninjutsu in 3 years is not an impractical idea.
Lack of initial skill is nothing in the face of hard training and a great sensei. Madara did have contact with tobi, and if tobi is madara, training and teaching is definitely what took place. All that he learned in 3 years was how to use sharingan and a space time ninjutsu (to our knowledge), and if he was rolling with madara, this was definitely not an impractical feat.
Tobi is not the Elder son. First and foremost, and probably all I need to say, even though he is the uchiha elder, he did not have the sharingan. His dojutsu was more similar to rinnegan than sharingan. right there should be enough evidence, but I can share more. If tobi was as wise as the elder was, I feel like he would have known that minato was smarter than to just run into somebody who he just figured out was invulnerable and had run through it twice. Even I would probably think the third time if he does the same thing he probably has a plan. That was an unwise move by tobi and I dont think someone as old as the elder son would be as unwise. And I believe that being the son of the so6p would make you faster than any other person, yet minato escaped with ease his attack without using space time ninjutsu. That just doesnt seem like something possible against the son of the strongest ninja ever. And why would he pose as madara? Madara must have been weaker than him, and he at least smarter than madara if he taught madara everything he knows as you said. It would be much more intimidating for him to say I am the son of the creator of everything you know.
I may not be correct in my guess, but at least i have evidence to back up my point. He's just not the elder son. My first point on that part should explain enough.
first i want to say that i appreciate you reading my post and taking the time to respond. i wanted to pay you the same courtesy.

you shouldnt assume that the one picture we have been provided on the sages elder son tells you everything you need to know.
images can change...for instance...
the ten tails then...

these arent real images like looking at naruto and tobi on the battlefield. these are images of what someone imagines they may have looked like. who alive in teh naruto story could even DESCRIBE what the rikudou's sons looked like? hell most of the ninja world considers the sage of six paths to be a myth. even kakashi was in doubt when he heard the story.

you talk like you know about the elders son's doujutsu as if that defines him.
what was his name?
how much older than his brother is he?
When did he die?
how did he die?
who was his mother?
...the point is that you dont really know anything about him. so its difficult to say that tobi is definitely not the elders son. if you cant put real evidence against him, then he is still a possibility. a picture doesnt define someone. look at kakashi for instance...he keeps his face covered every moment we've ever seen him. hair styles can change, and apparently even eyes can change. if he had one pair of eyes, maybe he lost them, or traded them up. if hes been alive hundreds of years maybe he has replaced body parts or changed hair styles a few times. we know for sure that he has changed masks at least 2x like was said. also i would ask you to remember that the sage became a living god because he was the jinchuuriki of the juubi. it stands to reason that his son would be powerful, but not of the god like power that the sage possessed, as the sons were not (as far as we know) jinchuuriki's much less the jinchuuriki of the juubi. also, lets remember that learning space time ninjutsu is not easy or even necessarily possible. kakashi took years to create and perfect his kamui and be able to use it. I believe he developed it off of the tsukiyomi that itachi put him in. he is the copy ninja and created the chidori... if space time ninjutsu was easy to learn, why hasnt madara used it? why hasnt sasuke or itachi learned it? some eyes have some abilities...its obvious that tobis sharingan eye that he prefers to use, has the ability of space time jutsu...his invulnerability isnt something to be underestimated... who else can do that?? name one other person in the whole series that can become ethereal! i love it!
what im doing is not taking tobi's name or the way he looks to define who he is... Im taking what he believes in, what power ratings he has, how other characters perceive him, what level of knowledge he has about different subjects, and im making an educated decision. some of it is fact based and other parts are intuitive. the real defining trait about tobi is his complexity. he has more power, knowledge, and longevity than anyone in the series. This places him in a position of power. He can pretend to be whoever he wants, and no one can deny him that, because they cant get ahold of him and force him to do anything. name one thing that anyone has ever done to force tobi into doing something against his will. name one time that anyone really surprised him. name one time that he was in a situation where he wasnt the one with the knowledge and power. you cant do it. he got over confident fighting Minato, that is true and obvious. Minato was chosen to be hokage and became a legend for a very good reason. minato was a one of a kind ninja. he stopped tobi, stopped the kyuubi and saved the village. all while empowering his son to be able to do the same thing in time.
the issue is that tobi can be ruled out of being just about everyone we know of...except the sages elder son...
