Like Jason said, WMP11 needs more work, but isn't utterly useless. If you compare the first beta with the release version, you can see a great progress. I know I have made some serious comments about WMP11, uttering that it was crap when it was still in beta. But I feel it has improved a lot. My biggest gripe was that you couldn't use WMP11 without a mouse, that keyboard navigation was impossible. But they have solved that pretty good. You can tab around and reach all the elements.
