pages, or swift publisher.
I checked swift publishers site, but I can't tell- are you able to import and export Microsoft Publisher files?
What everyone is trying to tell you is not to use Publisher. Nothing outside Windows can open Publisher files. It is a gross imposition to send Publisher files to users who do not have the Windows version of Office.I just really need something to create brochures and can handle publisher files. I guess if I can't find anything I'll just use VMware Fusion
Print shops hate Publisher files too. Then again, they probably wouldn't wouldn't appreciate a Pages "file" either.
You might also consider PageStream which is available for OS X, Win, Linux, and Amiga.
I believe that is PowerPC only, which would make it an extremely bad choice for anybody on an Intel Mac.
