Mi productivity set is console-linux based:
blog - once a week (in Spanish), as a Sunday relax
"todo" files - always .txt in vim.
calendar- wyrd (with remind)
web- Scrapbook the site to see it in a proper time (in that case I use firefox or konqueror)
rss- once a week with akregator.
notetaking- always in .txt in vim.
With that, 80% of my activities are console controlled very quickly using commands. A real time-saver for me, indeed!
