Palm OS

yes, the treo can handle that. if you are a microsoft office user, there is an application that comes with the Palm OS desktop software called, Documents to Go(DTG). it allows you to view/edit/create documents in either a mobile format for just your device or view/edit/create documents in the native microsoft office format so that you can take it between your handheld and computer and not lose any information or functionality.

along with Word, DTG is able to do all of that with Excel and Powerpoint as well. in Excel you can create macros and algorithms the same was as you do on your PC. it's fully functional. i have run into some limitations with powerpoint, but that's understandable with the limited space/processing power available in the treo.

so to answer your question... yes. you can use the treo as a mini word processor... only problem is your thumbs will get tired rather quickly. i know mine do.
