Microsoft’s office is the ‘standard’ office application, but not something I’m willing to spend money on. On Windows, OpenOffice 2.0 is excellent, and as a user is very similar to MS Office 2002, with good compatibility with MS’s version.
This comes in two under-developed versions on the Mac, one official one that uses XWindows (a *nix windowing environment), and an unofficial one based on Cocoa called NeoOffice.
Read the Mac download page for the info, I’m trying the Neo version first, I’ll see how it goes.
Other PDF apps are TextLightning, a Mac OS X native utility for converting PDF files to RTF format.
Little app for removing formatting from the clipboard cut and paste.
