Hot on the heels of its OneNote app for the iPhone, Microsoft has gone ahead and given the Android Market a similar nod of acceptance with the release of OneNote Mobile. Like the iOS version, the app is free to try -- which allows tire kickers to create up to 500 memos -- but after the limit is reached, you'll need to plunk down $4.99 or be forever stuck in read-only mode. In addition to syncing all notes with SkyDrive, the app allows users to open notebooks from OneNote 2010. Android 2.3 is necessary admission for this one, and naturally, all users must have a Windows Live ID. So, Google, are you going to just stand there and let Evernote and Microsoft have all the fun?
