Does Cobb’s totem keep spinning at the end or is it about to fall off the table?
A: The fact that the film cuts away before we know for certain suggests that they want us to keep guessing. But we think it kept spinning. Here’s our reasoning: Note that at the end of the film Cobb’s kids haven’t aged. They match exactly his memory of them. A memory which must almost surely by now be out of date, since he’s been away from them for many months. Though he finally sees their faces, otherwise they look exactly as he envisioned them. They're even wearing the same clothes. In reality, his kids would now be older and different than his memories of them. This could suggest that Cobb is still in the dream and the top does indeed keep spinning after the credits roll.

Alternate Theory Aaron points this out in our comments section: "In the opening moments you get a glimpse of Leo's hand. Specifically, he's wearing his wedding ring. Now, if you follow the rest of the movie keeping an eye out for this you will notice that he only has the ring on when he's in the dream world. At the end of the movie he isn't wearing the ring." If the ring only appears when he's in a dream and he's not wearing at the end of the film, that could be confirmation that in fact, the top does stop spinning after the credits and Cobb is at last in the real world.
