There is a big learning curve for new comers, but the rewards are very high and it's designed to work simply out of the box.

Here is an introductory talk

To get setup

And since orgmode is basically text files, for the first time in my computing life, a two way sync actually works. Any file comparison program can compare the text files, so modifications on a pc and the handheld can be easily compared (I use kompare)

I've tried lots of "gtd" apps - life balance, bonsai, shadow, datebk6, outlook, eccopro (best ever, not great with linux), the tiddlys, the batf, etc. Orgmode on the n900 is the real deal.

For contact management, bbdb works well with emacs & org; now you can text & call directly from emacs!
