I have been using the Outlook notes, and they were sync'd into Toodledo with the windows sync app. This works.
Recently I tried Evernote and it just seems a lot more powerful. It would be nice to have that sort of capability rolled into Toodledo so I don't have to have yet another app/website to sync.
One of the big features that I didn't really think I would use is capturing a photo as a note itself. This is handy in so many ways...
-we have a nice diagram drawn on a whiteboard and I need to save it (sure I could just take a regular photo, but then it is stored with all my family photo's and that isn't a very usefull place to be used as reference
-capture a menu to have on hand for later
-capture a post-it note so it is always with me and I don't have to type it in
Obviously, photos would eat up a lot of storage space compared to the text only notes/tasks you guys have now.
