Hopefully everyone can now be happy: Safari 3 allows web designers to style form controls with CSS. The results are pictured: instead of a glossy, Aqua-like control, Safari displays a matte-finish control in the color and size of your choosing. You can even apply background images to form controls. If you don't apply styles to your controls, then Safari retains the Aqua look.
This shouldn't require any changes to code that's already written for other browsers: Safari 3 should pick right up on the formatting, and display it as the designer intended. It does, however, open up WebKit-specific CSS to your form controls.
