Was that 400 total owners, or 400 that replied to the poll?
Good points. You will always have the problem of people only answering surveys they are interested in.The trouble is that the results are still going to be skewed - firstly due to the people who are likelier to respond are those with broken 360s, and secondly due to the people who read the forum in the first place.
However, in this case, you have a good method of approximating to the total number of users. If we assume that the number of people with two or more failures is in the same proportion to the number of people with one failure, as the number of people with one failure or more is to the number of people with a machine that hasn't failed, then we will probably be close to reality. If anything we'll probably be slightly low, due to replacement consoles having had less time to fail.
Which, in the survey Rod_S linked to, looks like about 32% of users with one or more failures. It's an approximation, but I think it's a fair one, from those figures.
