Just how are we supposed to dress for success anymore?

Jon Rubinstein from HP's Touchpad launch.  Jeans and button-down.  Fine for those already at the top of the food chain.  For those on their way up do you:

1. Take the traditional path - e.g. wear a suit and until you get there?
2. Dress like you're already there - e.g. ditch the suit and wear jeans?
