I'll dissent with the common opinion. I'm sort of like Imran with my conditional operator style. If it fits cleanly on one line, I keep it on one line. If it doesn't fit cleanly on one line, I do break it, but I use only a single tab (4 spaces; I have VS set to insert spaces for tabs) for the indent. I don't immediately jump to if-else, because a lot of the time the conditional operator makes more sense contextually. (If it doesn't make sense contextually, however, I simply don't use it.)
Also, I don't nest conditional operators. At that point, I do find it too difficult to read, and it's time to go to the more verbose if-else style.
