Windows Mobile 5 and Pocket PC devices are only suitable for:
- Reading email on the road.
- Seeing (and maybe updating) your calendar on the road.
Priacta discourages Windows Mobile 5 for managing tasks. The technology is slower and far less reliable than newer options. Consider upgrading to a phone that works well with your ideal task list. (This is a good time to choose a new task list, if you are considering that.)
