My Brain. It's easy when you know how.
Likewise.
Normally I just remember, but sometimes I scribble down a note on my sketchbook.
Fall back option.
I use my iPod Touch as a PDA. I've jailbroken it and I have a ToDo list, notes, editable iCal, etc.
Interesting. I am considering trying out a Touch for this purpose. But I am not holding my breath.
Over the years I've used the Newton, Palm and Pocket PC devices. My favorite was the Newton. However, the Newton 2100 is a bit big to carry. The Palm and Pocket PC devices were okay, but did not fit my way of doing things.
Now I am back to paper. I use an old PC calendar program that does what I want, and I can print out 6 week calendars which I need for my job.
I have a way of folding the paper so it fits nicely in my jean or slacks pocket or on the inside suite pocket. Just requires a pen/pencil to use.
For me, being able to see a 6 week schedule allows me to project and plan. I simply cannot do that with any electronic device except a PC computer with a big enough display to see all 6 weeks.
For to do's, there are two types overall for me. The next day or long term. At night I write down the next day ones the back side of the calendar. For the long term (those occurring more than a day away) I have a nice Microsoft Word table that has 6 major areas. Four of these are work related and one is personal. The other is a simple info area with important information that I need on a daily/weekly basis. I usually update both on a weekly or more basis.
Currently, this system works best for me. it requires very little space and I can practically use it anywhere. It's easy to carry, functional, accessable, and is cheap.
