100% agree as a fellow frequent flyer. Additionally

1) I find that general boarding involves several minutes of just standing in the jetbridge waiting to get on the plane, which is completely lost time. This is often true on popular routes right up until they close the door.

2) If you board late and you're not in an aisle seat you're going to have to deal with the awkward "ask people to let you in and wait for them to shuffle into the aisle" situation.

3) Seating at gates is a pretty big problem at most airports, which simply weren't built to handle the number of passengers they now have. As often as not you're going to be standing at the gate doing email on your phone because there aren't any comfortable seats available.
