In a very uncharacteristic move. Microsoft has made OneNote completely free. If you aren't familiar with OneNotes, its basically a note taking type of application similar to Evernote (which is awesome and basically taken control of the 'note taking' applications).
I assume in effort to compete with Evernote, Microsoft has made OneNote free while pushing their cloud service advertising a 'OneNote to Bind them' type service.
Hate to say it, but it actually looks promising, once you sign your soul over to Microsoft that is.
Now available for Macs, iDevices, Androids, and Windows.
