Keeping the housekeeping matters

[From Ronald Abadi Surabaya, East Java, Indonesia] Occasionally, I need to jot down some housekeeping matters such as expense records, to-do list, thoughts, etc. It is certainly nice to have these information on my PDA Phone since I do not leave home without it. Whenever and wherever I need to remember something or have any thoughts, I just put them on my PDA. I do not use any particular software, just Pocket Word included in Windows Mobile 2003SE.
