Well said, Dylan! And the beauty doesn't have to be skin-deep either - the product might be emotive, elegant and inspiring, but it still needs to be usable. As I said in one of my posts, a usable site can arguably survive without delight, but a delightful site relies on usability for it to be such.
@DMG - I think both Matt and I agree that 'delight' is the pinnacle UX designers must aim for. However, I believe the foundations of a project need to be built on usability for it to get there.
