Hello. I'm a student and new to GTD. I have a Mac at home which I have been using with an Excel file to manage projects and Next-Actions by using color coding and marcos to quickly label and identify Contexts.

I will soon begin working a full time job and at the office will be using a Windows-based laptop. I also want to get a PDA so I can have my project list and other GTD reference materials with me at time.

Has anyone figured out a good system for using all these tools (Mac at home, Windows at office, any PDA everywhere) with robust syncing, seamless (or close to it) transferability and interoperability between the 3 systems?

If you have, I would greatly appreciate you telling me what software, PDA model, and paper based tools you used to make it all work.

Thanks Mucho
