I'm currently using ListPro to do GTD on my PocketPC. I backup on my home PC and occasionally enter data at home via the keyboard, but most of my data entry is on the fly. My home PC has been dying a slow, ugly death and will most likely be replaced by a Mac. Unfortunately, ListPro isn't available in Mac, and out IT guys at work won't allow installation of user-purchased software on the company machines.
So what are my options when we finally take the home PC out and shoot it?
As I see it, it's either to find another app that is both PocketPC and Mac compatable, or run the risk of no data backup on the PocketPC.
