Sure, it'd be cool if everything was perfect. Then we wouldn't need to write all these tests
$ cat src/wine/*/*/tests/*.c | wc -l
1085766
But we don't live in that world and it's far more interesting to compare like with like. When you take into account its scope, in terms of completeness and usefulness, MSDN is head and shoulders above every other API doc I can think of except maybe Java, which is also excellent. Certainly better than Apple, and don't even get me started on most open source APIs.
