Completing the 3-app trifecta, Microsoft’s OneNote is now on the Mac App Store. I have a handful of friends who used to adore this app back when they were PC users, but now use Evernote. Personally, I’m more of the one-app-per-function persuasion: OmniFocus for tasks, Simplenote for notes, not-sure-yet for shared lists, Paprika for recipes, Pinboard for bookmarks, and Fantastical for my agenda.
