Documents to Go Professional Edition gives you the ability to edit Microsoft Word and Excel documents and other files on handheld devices with Palm OS 3.0 or later installed (the previous version allowed you only to view files). Modified documents are easily synchronized back to your Mac, and they can also be beamed to other Palm OS handhelds. (Handhelds without Documents to Go cannot then HotSync to a desktop, however.) When copied to a handheld, files retain most formatting, including bulleted sections and tables in Word, but Palm OS doesn't support multiple fonts. Although the small Palm screen can make working with spreadsheets awkward, the software makes navigating cells easy.
