Acrobat seems to be the only one under Linux that works well with PDFs

nearly 100MB for the viewer has annoyed me somewhat.
Ghostscript doesn't seem to render with particularly good quality, and
all the other viewers I've tried seem rather incapable of dealing with
the physical size of PDF files that are wrapping document scans (I
assume it's another one of those situations where they're trying to
buffer the whole damn file into memory at once)
Presumably other Unix platforms suffer the same problems as they're
largely reliant on the same tools.
How Adobe mange to make Acrobat eat up 100MB of space is beyond me
though... :-(
I can't say I've found many bad TIFF viewers for single images though
(on any platform); it's only when multiple images are put into the same
file that a lot of tools start falling over.

It's
*could* - problem I've always found is that tools to handle multi-
image TIFF files are pretty thin on the ground; they either don't bother
at all (and assume one image per file) or they try and buffer the whole
lot into memory (for 100 A4 page scans in one file, that's Not A Good
Thing). Only about 20% of tools I've come across over the years actually
try and handle TIFFs properly (as I've said in the past, even
Imagemagick isn't great because it buffers data to 32-bit colourspace in
memory regardless of the actual images' bit depth)
The spectacular badness of TIFF viewers (at least at the free-as-in-beer
level) is why I prefer PDFs. Despite their problems, the PDF viewers seem
*way* better at rendering (and printing) the pages. (Though I am sure there
are other platforms which have no decent PDF viewer.)
