I rely on it all the time.

I LOVE having access to my OneNote notebooks. They are very complex, with pictures, drawings, clips from online sites. I am constantly referring to them on my pc and it is invaluable to have them available "in my pocket". Not a complete match to the pc as far as usage, but accurate on updates which is most portent to me. I paid for the cloud sync and it works great. Worth the fee to me.
