I am planning to switch to a MacBook. I need an application written for the Mac OS that will organize my files, web-clippings, notes etc. I collect a lot of informaton for teaching, research, and preaching. I have been using Ultrarecall in Windows. The searching ability of Spotlight will not be enough. I also need a way to group items into categories or projects. Maybe some sort of tagging feature would work. What do you recommend? What about Tinderbox, Devonthink?

Thanks for your help.
