That's true. And I do have a PDA around which I had purchased for my daughter to take to college but she ended up with a laptop instead. Thanks for the idea; I'll look into seeing if I can use it with my work network.
Well, my main point on focusing on electronic, and a single file (wherever it resides, or gets synched between devices) is that it reduces work. I find it easier to either type (as I'm a touch-typist) or do handwriting in a PDA. Once done, there is no paperwork to keep around, no scraps of paper. You don't have to transcribe the notes into another log elsewhere.
And on topic, I just went to a day-long training on Outlook today. The trainer seemed to agree with you that we should be concentrating on electronic vs handwritten. Maybe it's because it was a looooooooooooooooong day that I"m not quite convinced.
Actually, I find that it doesn't take up too much time, at least once you get in the habit of it. Pushing through into becoming a habit is the issue, I agree. I would suggest it be electronic (PDA, phone, notepad on laptop/desktop) vs hand-written (more work for you that way, and more papers to organize), and a single version of it rather than a file at work, one at home, etc.
ETA: Mind if I befriend you? I'll help me remember to stop by and check your wall.
Maybe you need a PDA and keep a note file in it with highlights of stuff you will probably want to remember, then keep it updated? At work, I usually keep a notepad up with information on what I'm working on, along with anything I should remember for the day.
