I love the Livescribe Echo II. Ten years ago, I owned an Echo, which I lost when I went to prison for 11 years. The Echo II is everything I liked about it's predecessor, plus all the improvements I wished for years ago.
I am still on the learning curve for audio recording, pen, and computer app synchronization and access. It appears that it may not be compatible with the current iOS app, only the iPhone and iPad apps. If so, this is a serious limitation.
