I agree about School Notes Pro. I really want to be able to use my iPad to take notes at work, send to my desktop, and keep them with my project files electronically, so I've tried out a bunch of the note-taking apps. I really wish I could combine the features of a bunch of them (and also some features of Good Reader) into one app, but for now, I've been using School Notes Pro the most. Right now, it seems to be the most responsive to my writing and have the best interface.
However, I would pay money for this app if they would get rid of the stupid advertisement that gets placed on the bottom of every note when you email them. It looks completely unprofessional. If they did that, allowed for the importing of PDF files to annotate, and could wirelessly link with the desktop rather than having to email notes, this app would be very, very close to perfect for my needs.
