When in landscape, the port on the right would be on the top. Since most docks are on the bottom, you are incorrect here. Do you understand how these docks usually work? you put phone in landscape into dock it has a landscape view and charges through the bottom (which is the LEFT edge). To use power on the "right" you would need to push up to charge and that would be a TON more difficult to design.
As for car mounts. When in landscape, your power port is now on bottom of phone FACING your expected power supply.
The power port was CORRECTLY put on the left side of this device. I still have no idea why this would be a problem unless you have a car mount that is not made for the Incredible.
