1. Guys, you are missing the point. This is not about redesigning the United website, it is about how to use Photoshop to design a web interface.

2. Nathan, why would you design something in Photoshop instead of directly prototyping it in html/css? I think designing straight in html/css is already pretty fast.

You also run into the danger of adding some nice looking effects that are easy to add in Photoshop but not so easy to implement in CSS.
