Not really a Palm OS program but a windoes desktop program which will let you not have to install a PDF Reader on ya Palm .... valuable if ya tight for space I guess.

PDF2Doc is a plugin for Adobe® Acrobat® (Windows) which can extract text from one or more pages and convert it to a format that is readable on Palm OS®, Pocket PC, Microsoft Smartphone and Microsoft Windows computers.

PDF2Doc will make it easy for you to take your PDF books or business documents and read them while on the go without having to waste precious space with the Adobe PDF Reader. PDF2Doc can automatically transfer your converted documents to your handheld device.

NOTE: This plugin will work only with the full Adobe® Acrobat® program and not the free Adobe® Acrobat® Reader™.
