"OneNote has always been the black sheep of the Microsoft Office family. It's
far less well known than Word, Outlook, PowerPoint or Excel. And yet this
note-taking app, originally developed for the first generation of tablet PCs
a decade ago, is actually a good, solid, useful product that's recently been
updated and bundled with Office 2010. If you're on the road with a
smartphone, though, and you miss having easy access to the OneNote files on
your PC back at base, all is not lost. Microsoft has recently launched
versions of OneNote for Android, the iPad, and Windows Phone 7. They cost
around $15 each, but if you're prepared to live with a limit of 500 notes
then the apps are free."
