Microsoft's OneNote has long been available for Android (among many other platforms), but this latest update makes it easier to use specifically on tablets. The note-taking app now comes with handwriting support that takes advantage of the devices' relatively bigger screens, as well as with better options for formatting your notes. If you're going back to school soon and have a Windows device, though, OneNote for Windows sounds like the better choice with its new ink highlighter, printing support and ability to insert files and PDFs. Finally, the latest Livescribe+ update lets you set up a OneNote notebook where the Livescribe 3 pen can automatically upload what you're writing down on paper. All these changes are rolling out right now, so expect to get pinged for an update soon if it hasn't appeared yet.
