I was afraid it might be a little less interesting to this crowd due to it being a desktop app as opposed to a web app.
I view that as a feature rather than a drawback -- Many of my classrooms at school don't have wifi (and my school is rated on several "most wifi accessible" lists). Quickly navigating to a site to take notes isn't always possible.
That is a very astute comparison between this and a wiki.
It is similar in that you can create pages, organize them, and link between them.
It is more accessible to the average user than a wiki is - setup, administration, confusing options, etc.
This has fewer options - To do list, calendar, notebook.
1:The notebook is organized by one category (typically semester or subject)
2:Then you have a second defining category (typically class)
3:Finally, the entry for that individual lecture.
So it has fewer, more succinct options.
It is also more dynamic than a wiki. No university curriculum is limited classes where all notes will be in easily typed language. Imagine trying to take notes for a calculus class with just word.
I looked at my notes and realized that the reason I used a notebook to record my notes is because I needed to be able to draw graphs, write math formulas and chemistry equations - stuff that doesn't translate well to text editors.
So I build something that was as similar to notebook paper as it could be and still allowed me to save and organize my notes.
On the better grades front - I am convinced it was due to ease of studying that this afforded me. Usually before a text, quiz, or essay I was frantically flipping through hundreds of pages trying to find relavent notes. With this, I was able to simply search "LaGrange" and was greeted with a wider understanding -- Notes came up from both calculus and economics. I was able to understand the whole much easier since I was so much more organized.
