I agree, I actually think I'd love the movie a whole lot more if we got that extra second of the totem toppling and then cut to black. I know I wanted it to topple over.
Nah; I thought it was a good choice to do the final shot the way they did. The point I got was that Cobb has finally settled the question that had been plaguing him-- "What is real?"-- and has chosen to live.
The point of the final shot was to turn and ask the same question of the audience.
