I've implemented GTD with a Palm and Outlook at work and manage to keep my work and life projects and NA's separated in the same system.
At home I started going Open Source (to feed my inner geek) and I'm using Thunderbird for email, playing with OpenOffice and want to switch my NA's and Appointments to Palm Desktop (I haven't found an Open Source alternative that synchs those items).
The question is, does anyone have any experience synching the same Palm to two different back-ends? Obviously I'm just going to try it and cross my fingers, but I'd like to hear if anyone's has had any bad experiences with this. Thanks.
