One Note will, however, appeal to people who prefer 'structuring' over 'tagging'. In fact, if you prefer tagging, look elsewhere. The tagging support here is abysmal. There are tags, but they are canned and the user can't add their own tags. So you have 'Definition' and 'Idea' (which thankfully is not "Idea!") and 'To do priority 2'. And only the ones that the people at MS thought you might think were important. Even more bizarre, they seem to be only visual labels. You don't appear to be able to search for items matching a given tag. Wtf. Am I using a computer or not?
I will say that they seem to have nailed all the account management, in particular two-factor auth, for the 'microsoft accounts'. But they did this largely by copying google's two-factor auth stuff. Which, to be honest, is what I would have done too since it's pretty good. Anyway, they don't appear to have screwed that up. That's a plus and not super-easy. Separate from One Note though.
The tagging fiasco and lack of export are both unconscionable though and embarrassing, imo. They are not an early entrant here; they need to do better than the competition, not notably worse. Plus this is an old product for them, just new to the mac. Bill, where are you? Surely this is easier than Malaria.
