I use it mostly to just take quick notes like a name of a book or a person, maybe a phone number, this kinda things. With a 920 my way of quick noting is usually by just taking a picture and viewing it later, but naturally doesnt apply to everything. Gotta love a good camera
I use it all the time. Shopping lists, travel information - confirmations, travel docs, reservation numbers for train tickets and flights, work stuff, quick jots of names and numbers I'll need later.
I use it a lot because it can sync with skydrive and it has audio, image notes which are very important to me. Also it syncs very well with windows 8 has onenote which is a plus.
I use OneNote for my password list Because I do have a lot of websites to visit, and sometimes, I just forgot my passwords, so it's a big help for me. Rather than using a Third Party application, why not use OneNote? And lessen the memory captured?
Not as much as I'd like simply because I can't password protect my notebooks. In the lack of something like this in the Store, I'd like to use it as my digital diary/journal, but as it is, it's impossible. As far as to-dos go, my needs are a tad more complex than what OneNote offers so no can do on that matter either. Therefore, I only use it as my random note taking app. A shame really, as it could be so much more and still be a simple app.
