Yep. I guess he meant that this is how the checkout should be looking by default, so that those BO options (of those fields) will be disabled by default on a stock installation (while can be enabled by admin of course, if and when needed). One of the best marketing advisors I ever met once told me - simplicity is the key. The more you simplify your UI/UX and make important things stand out and be more accessible, the better conversions you will have.
Regardless of the one-page-checkout point , I think @ajensen27 made some valid points for improvement (and so did I :) ), and we always appreciate (constructive) feedbacks, whether we accept them as they are, modify them a bit, build on them or skip them altogether.
