Word processors and Desktop publishers are more than adequate
for documents of tens of pages.  Because they are mostly
limited to PCs and Macintosh, they may be impediments in
producing long documents, which would have to be done in
digestible chunks (say, a chapter at a time).  High-end systems
are usually UNIX-based, which means computer power and document
capacity are limited only by how much you want to spend.
