I've recently bought and read the GTD book and am very inspired and eager to start organizing all my obligations and thoughts into David Allens system. All computers around me, at work and at home, are pcs and I'm well accustomed to Outlook and it's calendar functions, but I'm ready to let it go if I have to. What I want now is a cell phone to be able to always have my calendar and my lists at hand. Thus it needs to sync well with Outlook. I figured they all did ok, but that windows mobile systems should probably do it better than the others for natural reasons. But after hours of googling I find that they don't even sync the categories for the tasks and events! And that surely is a must. I've seen tons of apps and stuff but I haven't found one that clearly points out that it can synchronize the categories (or folders or whatever could work in the same way) in Outlook and then group and filter my to do-lists by those categories. It shouldn't be so hard a task, and I certainly shouldn't be the only one with the request, or am I? Did you all solve it in another way?
Please let me know of your experiences!
