I like to have a ceramics plate underneath my ps3 so it doesn't heat up.
if you read the "Note" part of the section, it explains the risks and benefits of leaving it in vertical position. He suggessted to remove the disc and warned you about the ps3 may tip. Those two factors can damage your disc. Any movement while the disc is in the ps3 can cause damage, obviously in vertically position the system could shake or fall down with any movement outside. Ideally, vertically position is the safest but in real world accidents do happen.
