Architecturally it's a very impressive product and makes some pretty creative uses of the windows folder hierarchy to get it's job done.
I think OneNote was built with a crashfirst mentality - It is very hard to lose data w/ it. Their QA team is damn impressive too, I've been a follower of theirs for a while.
My only complaint is the lack of true real-time sharing ala google docs's Operational Transform (they didn't exist when it was made), but it does come close. Opening a shared notebook in class and having everyone collaborate on the note was an awesome experience.
It's inking support blows everything out of the water IMHO. It also has a lot of the advanced automation features you can access by integrating OneTastic.
Only real issue I've ran into is that it gets to be a pain to print with as it has some wonky scaling features and the page layout feels like an after thought.
It is also hard to get groups of people to use it effectively because it is basically a WIKI and needs to have the same kind of discipline / habits to make it usable.
If they can do inking support with Operational Transforms, they may be able to have a replay feature without even trying - something that many teachers seem to really want out of the product.
My friend and I love the product so much we've been trying to make our own online version with inking support w/ paper.js share.js, github, and localstorage.
However, although it's amazing compared to a pen and paper it's still incredibly frustrating to work with.
* It can't handle large amounts of handwriting without igniting relatively powerful computers
* It crashes constantly when trying to balance pen input with palm rejection
* Syncing doesn't really work with non-trivial merging and doesn't handle sync errors nor errors in general well -- all of these usually end up with handwriting layered on top of itself
* Syncing is basically out of your control, you can't do partial syncs when you really need a section/page fast, and large notebooks with handwriting can take hours to sync completely. I've basically resigned to splitting my notes into many smaller notebooks.
* Handwriting on the "Desktop" version is a complete joke and so you're constantly switching between the that and the app to get good handwriting and more features.
So it's great, until it doesn't work then it's a nightmare.
It seems like a fairly good product, although I really only use it for bookmarking tabs that Chrome seems to lose when it crashes/updates itself and nukes the "recently closed tabs" list.
Big fan of OneNote.
Edit: Vs. Office Standard. I have no insight into Home or Education versions.
Managing notebooks, tabs and pages is a real pain. I end up with a sprawling OneNote notebook that gets lost in the sprawl of OneDrive/SharePoint.
(I haven't tried that many things, but really I don't know of any decent competitor that runs well on multiple platforms, and does the basic things I need - which is text notes, other file types, and ability to tag and put into a notebook. And on a native app).
Maybe they are gearing up for a google merger or something. They are doing their mailbox app which looks cool and integrates storage and syncing. However, once again
1. Why would I use a mail client that only interfaces with gmail and outlook?
2. What is the point of the sync, this is default by most mail providers and clients?
3. Why would I want mail storage? I actually don't know what my mailbox limit is, but I certainly would not want to have the amount of .txt documents that could fill that up. Also, this is basic functionality. You can't pull me on your platform, google has the users you want and are better positioned, I still don't understand how you make money as a company.
Syncing. This is a default piece of all browsers, the 2 main operating systems win/os x, and comes standard on most phones. This is like the browser, you can have it for free so you stay in our ecosystem. Mega GIVES you 50GB of storage completely free NOW, and it is likely more secure. I don't know enterprise as well as I know consumer, but at some point I would imagine the choice is between buying a few SSDs and having an internal server, or setting up your own secure system via VPN. There can't be much room for this.
