I'll vouch for dead trees - compare and contrast the MacWrite document from
some variety of Mac that dealt with single-density disks with a Gutenberg Bible
<http://www.huntington.org/LibraryDiv/GutenbergPict.html>. One is suitable
(after removing the metal door) for use as a coffee-table coaster, the other is
legible, and to a certain degree, intelligible. (more difficult than texts in Europanto,
easier than Beowulf in the original)
