You might try using MemoLeaf http://www.redwood-creative.com/softwar2.htm on your Palm to implement the CyberPoche http://avm.online.fr/cyb.html method. This would require you to (probably) sync only from your W98 machine. Although you did not like not having the ability to sync with Outlook, unless you wanted to keep your office emails on your Palm, it should not be a great burdon to duplicate your office "stuff" on your Palm. CyberPoche only requires DateBook and MemoPad (MemoLeaf uses it), and I have found that having all my addresses on my Palm is a VERY good thing. Yes, there would be duplicate entries. However, you would also have a backup device (your Palm) that would contain your GtD system in case the laptop was lost/ stolen/ broke.1. Is there a better way that you can think of?
There is a freeware implementation in Excel http://www.bellc.com/productivity_management.html that may be up your alley. Sorry, I just found it the other day, so I can't speak to its quality. But the price is good. If it works for you, you can keep the Excel spreadsheet on a floppy or a thumbdrive and carry it with you everywhere. A search for '"David Allen" "Getting Things Done" software' on your favorite search engine might give you some other possibilities.2. Is there an existing template/system already designed in Excel or Word?
I would keep 2 parallel email systems. I have (at my office) Outlook email, and personally I use Yahoo email. As long as you check both inboxes, I doubt that you would have any problem. Unless, that is, your job requires you to receive and reply to many emails from both sources each day.3. How would I integrate the emails into a Word/Excel format, or is it better to have 2 parallel email systems?
