In response to a few posts about the totem and the ending:
(SPOILER)I think the totem only works as an indicator as to whether you are in someone elses dream. Since each individual knows how thier own totem works it will not work in thier own dreams. Since totems are ordinary objects with a slight unique variation if you are in someone else dream they will act and feel like their ordinary counterparts, but in your own dreams you can subconciously manipulate them to work like thier unique counter parts so they are no indication that you are dreaming. As such there is no indication at the end as to whether Cobb is in reality or dreaming

I also think the point of Cobb's totem was that in reality it was designed so it doesnt stop spinning. In the dream world it would topple at a normal rate which is shorter than it would in reality

However if that is not the case (edit, now that i think about it, it likely isnt the case) then Cobb's totem is strange in that it works in the exact opposite way as the other totems. Where the other totems are normal items with strange properties in reality (dice is loaded, chess piece has a hole in it) Cobb's totem is a normal item with strange properties in the dream world (spins forever) which doesnt make as much sense as a totem indicating when you are in someone elses dream. It could only work as an indicator of whether you are in your own dream and even then it can only give you a positive result (if it spins forever) and not a negative result, as if it topples you cant tell if it was your subconcious toppling it
