There are several recent threads and posts in other thread about transporting the TV laying down. Nothing has changed in the past 12 years - it's still not advised to transport a Plasma laying down and all the manufacturers still say to transport them upright, and specifically advise against transporting them flat.
They may weigh less than before, but the thinner cabinets and flimsier chassis and lack of protective outer glass on the new models makes them even more susceptible to cracking while being transported laying down.
The packing in the box supports the bottom of the TV when upright, but there is no packing to support the center of the TV when it's laying down so it can sort of "bend" in the unsupported middle. Many of us have transported them laying down with no ill effects, but just know that doing so greatly increases the risk of cracking the panel.
