Low Tech Collection and High Tech Organization
I do what David does--when taking down a phone message or other information it is usually easier to write it down on a pad first. Then, I decide if it is something I can knock off in two minutes (like return a call to someone's voice mail to leave information, etc.) or if it is something that belongs on a list.
If I decide to put it on a list I have two choices--toss the paper into my In box for later processing, or load it directly into my PIM. To make the latter easier many PIMs come with a memory resident utility that speeds this process. ACT! has SideAct that will let you quickly enter something into the ACT database without having to load the main program. Outlook comes with the Microsoft Office Shortcut Bar (it's free with Office) that creates an (autohiding) menu bar that lets you instantly bring up an Outlook Task form, Contact form, etc. that loads into Outlook directly.
IMHO a lot of Outlook users neglect the utility of the Office Shortcut Bar which is a shame. It's a really nice utility. There were some problems with earlier versions (which would occasionally disappear) but the version in the current Office Suite is, in my experience, rock solid.
I seldom enter information directly into my Palm device. It's much easier to use the keyboard of my PC for entry. Once something is in the Palm, then using Grafitti to make the occasional modification is easy.
If I were on the road a lot I would take information down on a pad, then either do it or toss it into my moble "in" file and handle it as above. When I am traveling I do use a portable thumb-board for my Palm which makes it much easier to enter text if I'm away from my PC.
Low tech vs. High tech --- depends what for ...
To register notes , I still use paper, and I barely write down in the palm.
I use a lot the desktop version to enter during thje day the info. But after working hours the palm is basically a "read-only device" for me ... of course I syncronize more than one time during the day.
