Jeez. Doesn't ANYBODY trim?

And some of the existing equivalents
do not seem to be able to render documents
in a way that the looks are decently similar.

M$ keeps moving the goal line.
Even M$'s own stuff isn't backwards-compatible with "itself".
OOo has a reputation for being able to open Office documents
which M$O thinks are too broken to open.

Some things that would be replaced, if possible:
Word, Excel
(only i want the capabilities that the DOS version of Quatro had

OpenOffic.org (Calc)?
A guy even has VBA working on OOo.
