Microsoft OneNote, part of the Office suite, is Microsoft's alternative to Evernote, the popular digital notebook that we covered in our Android Productivity Apps slideshow last month. Like EverNote, OneNote enables you to gather and save all of your notes, URLs, ideas, pictures, products, news and more in one location, so you can find them more easily in the future.
OneNote lets you create searchable notes that can include text, bullets and pictures. You can keep the notes in sync using Microsoft's SkyDrive storage service, which then lets you access, edit and manage them from virtually any online device. The free version of OneNote is limited to 500 notes, with unlimited use available for $4.99 via an in-app purchase.
