Now that the USGA has ok'd the use of laser range finders (I know they are not legal professional competitions thus far) I could not agree with you more. They can get their own yardages instantly so they should not be slowing up play. As a matter of fact, I think the players should be required to carry their own bags, makes golf more of a "sport".
The better condititioned players should have an advantage.
The player should be determining their putting line and deciding what club to use without consulting with anyone else. You can't ask a competitor what club he hit, why should you be able to ask your caddy?
