Ask Slashdot: Logbooks and note-taking

leonstr writes: I'm a sysadmin and I like to record my daily work in a logbook: technical notes, work progress, actions from meetings, etc. I started with the word processor on the venerable Psion Series 3a but for about 10 years I've been using Amaya (http://www.w3.org/Amaya/). It's FLOSS, cross-platform and uses an open file format (XHTML).

Amaya has its quirks but I really like it, unfortunately it's no longer being updated and I feel it's time to change.

So I wondered: what do other people use for recording their work? What works well and meets your requirements?
