I will use my Iliad [in near future
] for reading "scientific" pdf-files [converting tex -> with dvipdfm -> to pdf].
LaTex ist
the format for publishing scientific texts. It's a horror to write mathematical equations in office suites like Word or OpenOffice.
It's easy to change the page size in latex-files - just change the preamble & your dvi-file get's a new perfect layout.
To make it clear: LateX files are txt files with layout instructions.
We will see how readable it is to read pdf-files published in A4 format on an A5 screen. Yes, pdf is page-centric, because it's a output format for printing on paper.
Dismissing the concept of pages makes no sense for me. This is how a printed book works: text
with layout. I hope reading with the iliad will have the same reading feeling like printed books.
