We reported previously on the OneNote app, which I briefly reviewed (the WP7 version) in my HD7 review. My impression is it's a sort of dumbed down Evernote (without the fancy website scraping). You can now sync and track your bullet lists, to-dos and even embed pix in notes on iPhone (requires a Live ID--app will help you create one). This is a reminder that you can still get the mobile iOS app for free in the App store (limited time).
