For many years, whenever I had some notes I needed to take or keep (such as in my undergraduate years in college), I used a full-fledged word-processor (e.g., Microsoft Word). This worked for my needs, but Word wasn't really designed for taking either on-the-fly notes or the more formal notes required for a class or meeting. Responding to this need, Microsoft introduced OneNote in 2003. This application was created specifically for taking notes (in text, pictures, and voice or audio recording). Your Windows Phone 7 device ships with a special version of OneNote that includes the special ability to synchronize your notes to your Windows Live SkyDrive account, letting you take your notes on the go and view them on your computer later (or vice versa)!
