I Thought Susan Boyle sang well.

I thought the best act definitely won.

And I thought that while the final two acts were waiting for the final result, she seemed to be really unhappy and was shaking and finding it hard to keep it together, and it seemed that she didn't want to be there, until the result was announced, at which point she seemed to relax and looked genuinely happy and relieved that it wasn't going to be her in the spotlight any more.

The others were all much of a muchness.
