I wrote yesterday about Microsoft releasing a free version of its note-management program, OneNote. I mentioned that this was a traditional desktop program. If you haven't grabbed your copy yet, see http://www.techsupportalert.com/content/microsoft-releases-free-version-... for the story.
Jojo Yee helpfully reminds me that there's also a new-style Metro version of OneNote too, if you're a Windows 8 user and you prefer such programs to desktop apps. You'll find it at http://apps.microsoft.com/windows/en-US/app/onenote/f022389f-f3a6-417e-a... and it's also free. You'll need to download it from the Windows Store, for which you'll find a link on the page mentioned.
