I fooled with OneNote briefly and couldn't figure out why I'd want to add it to my tool set since I already had MindManager. A post to a MindManager yahoogroup today captures my impression:
I have yet to find the 'killer app' to move me from MindManager as my default tool for whatever problem or process I am working on. I also found OneNote's on-screen metaphor of physical pages & tabs meant that most information was invisible most of the time - a real step backwards from MindManager, I feel.
MindManager continues to be my tool of choice for working out ideas, gathering and organizing information, and planning.
The new Dell Latitude X1 I'm using for work is really nice. Love the light weight and NO FAN! The light weight means less stress on the machine when moving aroudn with it. I wish I could say it makes my computer bag lighter, but I tend to carry books, papers, and other stuff in their just about to capacity anyway. But, when I travel, I tend to cut down on that stuff, so I expect it will pay off there. Maybe I'll look for a lighter bag! Oh, and it's wireless range is definitely superior to the Latitude C600 I used before.
ActiveWords. What a great tool. How did I get by without it? Go download a trial copy. If you do any reptetitive keyboard tasks, use common paragraphs, etc., you'll love it.
Finally, I've quit using my pocketpc. I experimented with one, but it just doesn't deliver enough for me. I don't even keep it syched due to a shortage of USB ports. I do like having my calendar and contacts with me, but not at the expense of carrying another device. Maybe a bluetooth enabled smartphone next time?
