Beat me to it... But I couldn't agree more. I would be most interested in the Word document and integration of OneNote. I don't like they way they have it setup now as that you have to have an ms account. Leave it open, integrate with dropbox or skydrive and I would be a very happy camper. Those are just some of my personnel comments on how I would like it seen implemented. If it does come true.
I agree, I hate how all these companies make you make an email account to use their services.
And yes, I know that's not really solvable, but it's still annoying.
