Linux users will have to have Wine installed
No they won't, cuz Linux kicks ass
My version (Linux Mint 7) can handle rars, zips, pdfs, and all that jazz without installing anything. Actually, it can open just about any type of file straight away, right out the the box, without installing any stupid software. I've NEVER come across a file that a bone stock Mint installation couldn't open.
For what it's worth, Adobe Reader more or less sucks. I love this one for Windows called pdfXchange. Google it. It's faster, less annoying (I HATE it when Acrobat freezes your browser when you accidently click a PDf link), it lets you mark up PDFs with a red marker and save the changes (USEFUL! - especially for parts catalogs), and it lets you easily take a picture of part of a PDF. It's a killer program, makes Acrobat look like dog turds...
Thanks a ton for the links. I've been using that Hungarian site, and it's pretty good, but not so well organized. We also have a list of hyosung parts catalogs here: http://www.hyosungsource.com/catalogs/
, but it's not so comprehensive, more something I just threw together for convenience. I think I'll throw a link to yours on our catalogs page
