zenjii, I have to agree with the others here when I say that an OS which is based on finger and finger gesture input is not going to give you the fine input control of a stylus based OS. Think of a finger input OS as writing in the sand with your finger. Yes you can make drawings and write words and equations, but they will be rather large in size because your finger is rather large compared to a fountain pen or pencil. If you tried to put your finger writing done in the sand onto a notebook page size of paper you would not be able to fit much of it on the paper unless you shrunk it down. so basically we are saying that that kind of note taking requires too much space when done with a finger and thus won't be easy to do on an iPad. But a stylus based system with a similar screen size would most likely work well, but only if the stylus is pointed like a writing pen or pencil and not fat like a finger.
