My favorite Projectbook feature is one Ive longed for in Evernote for agesthe ability to include sketches in my notes. You can draw or write with your finger or stylus in a variety of colors and pen styles. A handy zoom window is available for finer detailed work. For some reason, drawing seems to be confined to notes. Id find it very handy if I could also draw on top of imported PDFs or Word documents.

Both Evernote and Projectbook let you include images in your notes. These can be copied from other sources or brought in via your photo library, but Projectbooks image handling is more flexible; images exist in their own layer where they can be moved, resized, and re-ordered without interfering with the text.

Both apps also let you create folders in which to file your notes as well as tags with which to categorize them. (For the crowd, a set of GTD-focused tags are setup automatically.) A window pane appears on the left side of Projectbooks screen which provides views of your notes, folders, tags and to-do items by name. It takes up about one-third of the screen in landscape view, which is comparable to Evernotes approach. However, in portrait mode, Projectbook collapses it to a narrow ribbon, which I think is a nice feature. Evernote provides a thumbnail view of your notes, which I find very useful, so Id like to see Projectbook incorporate a similar feature as well.

Projectbook clearly beats Evernote in its task management features by letting you manage to-do items in your projects. You can create to-do items from scratch, but its more fun to let the language processing engine do it for you. For example, if you type call Fred next Friday into a note and then tap the Make To-Do button, when you switch to the to-do pane, youll find a related task scheduled for that day. If you create standalone to-do items, you also have the option of attaching a new or existing note to it. Marking a linked to-do item as complete also checks it off in its associated note, and vice versa.

As mentioned earlier, you can create tags to categorize your notes and tasks and you can also assign tasks to people, which seems to be just a special type of tag. However you can link your people tags to entries in your Contacts, which then lets you email tasks to the people youve assigned to them. And, as you might have guessed, you can also filter your to-do list by the person assigned.
