Note+ can be seen as an alternative to Windows Phone built in OneNote app, but while it is in the same broad app category, it's really serving a different audience. If you're the sort of person who keep numerous small text notes scattered around the place, then Note+ maybe the ideal app for you. It may not have the complexity of other note taking apps, but it does have a gentle learning curve, and is a very close digital analog to the post-it-note approach to keeping track of things.
The key benefit of the version 2.1 update is that it more deeply integrates with Windows Phone 8's platform features, making notes more accessible and "glanceable" (e.g. lockscreen and better start screen integration). The voice commands and voice dictation wont appeal to everyone, but they do make it possible to operate the app almost entirely hands free.
