I really like the idea of inline calculation which is a feature that's missing from Evernote and that exists in OneNote. Another feature that's missing from EverNote is FREE FORM NOTE TAKING. I would drop Evernote in a second for a platform that does freeform notes as well as MS OneNote does (disclosure, I use OSX primarily and thus I can't use OneNote natively).<p>I disagree with the "yet another" comment because the more high-quality choices there are out there the better. I think this looks like a promising product and, if nothing else, is a great way to see what the market wants because they will be able to make faster changes than someone like Evernote can.
