Getting Things Done

I first became aware of Getting Things Done from the 43 folders web site. While I've had the book for a couple years, I finally read it this week (along with installing OmniFocus on my work Mac). So far, I'm finding the GTD workflow to be quite helpful. Omnifocus, somewhat less so, other than as a trusted repository for projects. The big difficulty is that Omnifocus ties me too much to the Mac. On the other hand, there has been an announcement that OmniGroup will be doing an iPhone version of Omnifocus. That plus multi-computer syncing could make Omnifocus a really great product for my needs.
