Adobe this week announced that it will port its Acrobat technology -- the software behind its Portable Document Format (PDF) -- over to the PalmOS. Neither Adobe nor Palm Computing said when PDF would be integrated into the PDA-oriented operating system, but with the launch of a major upgrade to the PalmOS, version 3.5, planned for later this month when Palm ships its first colour PDA, the Palm IIIc -- we would surprised if the two technologies' arrival doesn't coincide. Fo course, Palm PDA screens aren't really designed to show the "tens of millions of PDF files already available worldwide" (as Palm puts it) -- basically, they're too small. Clearly the motivation here is Palm's strategy to expand its software at a platform rather than as the basis for one (its own) line of electronic organisers. Essentially, the move allows Palm to flog the PalmOS to third-parties keen to develop e-book systems. And Palm's goal is to shift its revenue focus away from hardware and toward licensing fees. Meanwhile, PalmOS 3.5 went Golden Master this week -- essentially wrapping up development work on the new operating system in preparation for its final release. ® Related Stories Colour Palm IIIc to ship 20 February -- Best Buy Samsung designs Palm-style colour ARM-based Linux MP3 PDA
